Spike was rushing through Ponyville, trying to get Rarity's while not being seen, he was hiding behind buildings, in bushes and even in the balloon at one point. Rarity was just about to unlock her door when she saw Spike hiding behind a bush.
"Spike!?", Rarity called out confused. Spike jumped and looked over to see Rarity, he ran over to her.
"Shh! I don't want anypony to see me", Spike said looking around to see if anypony was looking.
"Why ever not, darling?", Rarity asked. Spike looked at Rarity with a worried expression.
"May I explain, you know, inside?", Rarity could see how worried Spike was, so she unlocked the door and let him in while she followed. They sat down on a couch before Rarity spoke,
"So why is it you don't want anypony to see you?", Rarity asked Spike hoping to understand.
"Well, Twilight and I argued, I stormed out and now Twilight is looking for me along with Applejack and I don't want them to find me because they'll take me home, and I don't want to go back", Spike explained.
"Why did you and Twilight argue? And why wouldn't want to go back and talk things out?", Rarity was getting concerned as she knew what mindset Spike was in.
"Well, I didn't want to eat my apple because I was full and Twilight just got furious and said 'I don't understand you, I don't even feel like I know you, and friends are supposed to understand each other", Spike explained. Rarity was shocked but tried to help the young dragon.
"Spike, I'm sure she reacted that way because she loves you and she worried", then Rarity remembered something, "Do you recall what I said about remembering your friends?", Rarity smiled. Spike nodded.
"Yeah, you told me not to forget who my real friends are"
"Exactly, so---", Rarity was cut off by Spike.
"And now I know Twilight and Applejack for that matter, are not my real friends", Rarity's expression quickly changed into disbelief and sadness.
"Spike, why on earth would you think that?", Rarity asked.
"Well, as I said before, I feel friends should understand and listen to each other and Twilight said, she doesn't understand me, actually she also said she doesn't even know me, how can she be a real friend if she doesn't even know me?", Rarity had to hold back her tears, she knew exactly what stage Spike was at, and how vulnerable he would be at this point. There are so many things Rarity wanted to say, but she knew, from her own experience, it wouldn't help, so she bit her tongue and chose her words carefully.
"I understand, Spike, but I think Twilight just meant she doesn't understand why you... didn't want to... or lied about eating your apple, because friends shouldn't lie about sort of thing, she didn't why you would lie to her", Rarity said slowly, trying to not make things worse.
"Well... I knew she'd overreact, and I was right", Spike said a bit louder than intended. Rarity was taken back by Spike's volume.
"I understand, Spike, but what did Applejack do?", Rarity said, remembering that Spike said Applejack also wasn't a real friend.
"Well, she's helping Twilight look for me, if she was a real friend, she'd understand that I didn't want to go home and that Twilight was out of order", Spike said trying to keep calm.
"Spike, they're looking for you because they care about you, as do I", Rarity tried to reassure Spike.
"They only care about controlling me!", Spike blurted out. Rarity covered her mouth with her hoof in shock.
'Oh no! It's worse than I thought', Rarity thought to herself. Spike thought he made Rarity jump.
"Sorry, Rarity, I didn't mean to upset you", Spike looked down and faced his lap, feeling bad about his minor outburst. Rarity lowered her hoof.
"It's okay, Spike, I understand your frustration", Rarity placed a hoof on Spike's knee, he looked up to see Rarity giving him a comforting, but weak smile.
"Rarity are you okay? You don't seem... yourself", Spike tried not to use the word happy since he saw Rarity was trying to smile. Rarity put her hoof back on her lap before replying.
"I'm okay, I just care about you, Spike", Spike smiled, but then thought.
"Hang on a minute...", Spike stood up, Rarity was confused at the sudden change in mood.
"What is it, darling?" Rarity asked.
"You're pretending to care about me, so you can make me go home", Spike said pointed at Rarity.
"Spike I---", Rarity was cut short.
"Argh! You're all the same! Do I have any real friends?", Spike said heading towards the door", Rarity quickly got up.
'Oh no! What did I say?, Rarity thought while going after Spike.
"Wait, Spike!", Rarity called. Spike looked around in anger. Rarity caught up to him.
"What!?" Spike said furrowing his brow.
"Spike, I'm not pretending, I care about a lot because I---", Rarity was cut short by a knock at the door. Both Spike and Rarity looked around at the door, then Rarity looked through the small glass window to see who it was.
"*gasp* It's Twilight!", Rarity said pulling her face away from the window.
"WHAT!?", Spike nearly shouted. Spike ran as fast as he could and hid behind some curtains. Rarity waited for the curtain to settle, then she cleared her throat and opened the door.
"Twilight, is everything alright?", Rarity asked.
"No! Spike and I argued, he walked out and now I can't find him, have you seen him"
'Oh no!', thought from behind the curtains in a ball not to be seen.
"Hmm... I can't say I have, Twilight, if I see him I'll let you know", Rarity lied. Twilight came to a realisation.
"Oh no, if he's not here, that must mean that... he's in the Everfree Forest! I gotta catch up with Applejack", Twilight an off without even saying goodbye. Rarity closed the door and let out a sigh. Spike came out from behind the curtains.
"Why...why did you do that?", Spiked asked in shock.
"Well, not that a feel great about lying to Twilight, or the fact that my lie had led her to believe you're the Everfree forest, but I truly do care about you Spike, and I can see how much you don't want to go home", Rarity smiled, then suddenly both she and Spike realised what she had just said.
"Oh no!", said Rarity
"That means...", Spike continued
"They're both heading towards the Everfree Forest!!!", they both said in unison.
