Twilight, Spike, Matt, and Diana head to the hospital to test the crystal. The doctor sees Twilight and allows her to step inside, despite it being out of visiting time.
Entering the room, they see an orange dragon with red antlers trying to read the book. Matt touches Sunset's cheek to test her reaction. Sunset just stares at the inanimate stare and says nothing.
Diana flies near the orange dragon. Sunset just picks the cat up and stares for a while, then she asks. "Oh... who are you, little fella?" The orange dragon starts rubbing Diana's neck, making the black cat annoyed. Sunset smiles. "You are so fluffy."
Diana takes the shard of crystal and slowly puts it near her head. The crystal slowly enters the orange dragon's head. Sunset suddenly drops the black cat and holds her head. Others are concerned about her state and try to calm her down.
When she starts to calm down. Spike starts to ask. "You know what your name is?"
"My... My name is Sunset Shimmer."
Spoke points at others. "Then do you know any of us?"
Sunset just shakes her head. Matt rubs her head and sighs in frustration because this is not a situation he can deal with. Diana takes another shard of crystal and gives it to Spike. "Spike, give this and tell everything about this to 'Marshmallow'. I think she will send some of her soldiers to find."
Twilight glares at the black cat and tries to say something but Diana puts her paws on her mouth. Spike takes the crystal shard and leaves the hospital to write a letter to send to Princess Celestia.
Celestia is dealing with her court case. It is a good day for her when she has no complicated problems today. When the court is done, a letter appears in front of her. Taking the letter with a shard of crystal, the white alicorn reads the letter and drops it immediately. Then she heads to her guards to set up the search.
Luna feels weird when she sees her sister huddled up after reading the letter. When she reads the letter, the blue alicorn flies to Ponyville to visit the orange dragon as fast as she can.
When Luna arrives at the hospital, she is told that Sunset was brought back to the library. Luna heads to the library and sees the orange dragon reading some books while Matt and Diana are watching her. They see Luna moving inside.
Looking at the blue alicorn, Matt blushes and turns away. Diana smacks his back, then asks the blue alicorn. "Hello princess. What are you doing here? Don't you have your royal duty to handle it?"
"I'm here to visit Sunset." Luna moves around and looks at Sunset. The orange dragon just looks at her curiously. Luna asks. "Who made this?"
"A white dragon with cosmic wings." Diana shakes her head. "From what I saw, he's probably stronger than Arkon."
Matt is shocked when he hears that while Twilight is confused. The purple alicorn asks. "Who is Arkon?"
"Just a demon that Matt and his team have slayed before." Diana heads upstairs. "I forgot to take the sword. Wait here, Matt."
Luna asks Sunset about Celestia, about Equestria, and the many events that the orange dragon has been through but she receives an 'I don't know' answer. Luna decides not to push further.
The blue alicorn sighs in frustration. "Why did she have to fight that guy?"
"No information." Matt shakes his head. "We will need to search for her lost memory."
"You're right." Diana comes back with the white sword. "I believe that the crystal shard is not just in Equestria, but around this world."
Diana taps her hooves. "That's ... too much. Can you do anything?"
"Memory is not something that you can't make a joke about." Diana glares at Luna and points at Sunset. "We are holding a slow bomb here."
Luna gulps and steps back. Matt suggests. "We should take Sunset around this town to make sure that she won't be bewildered when seeing around."
Diana glares at him but Spike agrees. "That's a good idea." Spike helps Sunset stand up and asks. "Can we walk outside?"
"Uh... sure." Sunset nods. "I think so."
Twilight and Spike lead Sunset around Ponyville. Luna has to come back to Canterlot to do her royal duty and promises to make a searching team. When Luna exits the room, Diana levitates the swordsman up. Matt struggles with her levitation.
Diana demands. "Why did you make her into bait? You already know a stranger is looking at her."
Matt tries to retort. "But if we don't do that, I suppose we will get some information from him or her."
"She is a CLONE, you idiot." Diana drops the human and sighs in frustration. Matt stands up and rubs his back. The black cat grits her teeth. "I thought you had learned about mana sensation from Natalie. What is this result?"
Matt waves his hand. "You are not my mom." The swordsman sees a big dark claw with a killing stare from Diana. Matt runs out of the library. "Okay okay, I will fix this."
Matt closes the door hard. The black cat rubs her head and feels a headache from this swordsman. She can't believe that after stopping herself from destroying her world, the swordsman is still the same. This time it will be rough.
Spike and Twilight lead Sunset to Sugarcube Corner. The orange dragon tilts her head in confusion, then follows them to go inside. When they come inside, Pinkie Pie rushes into them and bounces around them, causing Sunset to be surprised. Pinkie Pie stops and asks. "Hey, I have created some brand-new recipes for my brand-new cupcake. Do you want to taste them?"
Spike rubs his chin. 'Sure. Let us... about 6 cupcakes."
"Be right back."
Pinkie Pie runs inside at high speed. Sunset just sits down and is silent for a moment. The orange dragon asks. "Who is this pony? Why is she so... Familiar?"
"Pinkie Pie is just doing her job," explains Twilight. "You just... don't take a brain to think about it."
"Oh... okay."
Pinkie Pie brings out the purple cupcake with some gems. Sunset just looks at it. The purple duo just told her to eat. When Sunset eats the cupcakes, she wants more and quickly gets another cupcake. The purple looks at her in surprise. Sunset blushes. "Sorry, the cupcake is so yummy."
Twilight and Spike laugh, then they order more cupcakes to eat. When they are done, Twilight pats Spike to ask him to do something. The purple dragon leaves the room looking for something. He checks the bush and finds nothing. The purple dragon rubs his head in confusion, then he ventures inside again.
On the roof of Sugarcube Corner, there is a yellow Abyssinian that looks exactly the same. She sighs in relief. "Too close, that dragon is more sensitive than I thought."
"And you are more suspicious than I thought, Sound."
The yellow Abyssian is surprised, then she turns around and sees a golden-haired human pointing the broadsword at her. The yellow Abyssian steps back and tries to escape. Matt slams the sword down on the group. The roof is a rising earth wall, blocking the way to escape. Matt throws a boardword at Sound immediately. It stabs into her head. The yellow Abyssian is slowly shattered into pieces.
Matt feels disturbed as a voice from behind the earthward yells at him from behind the speaker. Who is doing this? Please come out and surrender. We have surrounded this place."
Matt jumps on the earth wall and sees a coral mare wearing armor holding the speaker. The swordsman looks around and sees nothing, except some random ponies looking at the earth wall. The coral mare demands. "Alright weird monkey, get down there or I will drag you down by myself. You cause an earthquake and cause panic to everypony."
Matt knows this mare. She is the one who helps him in the invasion of the changelings. Matt doesn't want to be involved with this mare because he could get into trouble, and the mare is carrying a halberd. The swordsman pulls out a paper with a magic circle and places it on the ground. A magic circle encircles him and teleports him away. The coral mare notices the light and wants to jump on it, but it disappears for a second. She knows it is too late for that. The coral mare throws her front hooves on the air. "Oh, wow, more work for my guard."
Matt sighs in relief because he can finally avoid that mare. He suddenly hears a knock on the door. Diana opens the door and sees the coral mare.
The coral mare looks at the black cat and feels a tiny bit weird about it. She starts teasing. "Oh little cat, do you know where the golden-haired monkey is?" Then she starts patting the cat. "Aww, what am I doing? Why am I asking a cat to look for someone?"
Diana shakes her head and answers. "Because this cat knows where the 'monkey' you are looking for is." The coral mare is surprised. Diana slowly pushes the coral mare out of the library. "Since you asked me this, I will invite you out of this library. Thank you and good day."
"Wait wait..." the coral mare is struggling from the pushing. "I'm sorry. I never thought I would see a cat that can talk."
"Fair." Diana stops pushing. "Anyway, what do you want to do with this 'monkey'?
"You know. Since he ... or she causes panic in Ponyville and makes a mess on Sugarcube Corner. I just want him to clean up the mess."
Diana tilts her head. "Not in prison?" The coral mare shakes her head. Diana grins. "Wait here. I'll take him."
The black cat flies upstairs. The coral mare hears the loud sound coming from it. After a while, Diana drags Matt downstairs. The coral mare looks at him closely and recognizes him. "Hey, I know you. You are one of the humans who made me drive that big metal cart to the castle."
"Uh... yeah. I realize you do too. You are... Coral Blade, right?"
The coral mare nods. "You're right. Anyway..." the coral mare takes out the shovel and gives it to Matt. "Here, clean the mess that you have just created. Don't worry, I will talk to Mayor Mare about your residence."
Matt sighs in defeat and follows the coral mare outside. He just asks. "How did you know I was here?"
"Because this library is 'normal' for me. Many things happen related to this library, so I always come here first and ask."
"Sounds fair."
Matt looks at Sugarcube CornerThe guards around the stone are preventing the normal pony from getting closer, for fear that the stone may fall. The pony has already been evacuated from Sugarcube Corner. Matt blushes and starts cleaning up the mess. It's a great first day for him in Ponyville.
