I got the name of Total Vane from my Avengers X over called My Little Pony: Avengers Assemble though it is a different character from that story and has a different appearance
The next morning Silver Fork entered Rich Mansion and was then charged at by Harry.
"Fork did you invite anypony to my party without telling me?" asked Harry.
"Of course not Harry" Fork said annoyed.
Harry then helped him up and said "sorry pal but yesterday I found out my dad invited Twilight and Tiara invited those 3 'blank flanks' as she called them to the party!"
"Okay so it seems our sisters are taking the advice we gave them" said Fork "so things are going good with Twilight?"
Harry nodded and then said "I am going to go stretch my wings!"
When Harry went to fly he would so making sure no other Pegasus was in the air and in a place where he would be sure nopony would be watching. He would also hide his horn in the same hiding spell he usually used on his wings.
Inside the library Twilight was getting up and Spike showed her the response Princess Celestia had sent her for her last letter. The previous afternoon Princess Celestia sent a letter saying she would be coming for a visit in a few days and it would be on Harry's birthday. Twilight had sent a letter saying she wouldn't be able to be with her since she already promised to be at the 17th birthday party of a new friend that day.
Twilight opened up the letter and read it out loud:
My faithful student Twilight
It's always to keep to a commitment you make, although I would be disappointed not to see my faithful student much when I come to visit but nonetheless I'm glad you are still making new friends. I might even drop in if your friends let me of course.
Say to your friend I wish him a happy 17th birthday.
Princess Celestia
Twilight then put the note away. she then walked outside to see Applejack, Rarity and the Cutie Mark Crusaders.
"Can't believe Diamond Tiara expects us to accept her so called apology" said Scootaloo.
"but also invite us to her big brother's birthday party?" asked Applebloom "must be some kind of trick so she can embarrass us at the party!"
"wait Diamond Tiara has a brother?" asked Applejack.
"yeah I met him" said Harry "he's really nice!"
"what does he look like Twilight?" asked Sweetie Belle.
"He's a green unicorn" said Twilight "with glasses and a messy black mane!"
"Hey I think I see him sometimes talking to Silver Spoon's brother" said Applebloom.
"Me too but he doesn't look like Diamond Tiara or her parents" said Sweetie Belle.
"He's adopted" said Twilight "he told me Diamond Tiara's family found him and raised him when he was a small foal!"
"Do I have to go Applejack?" Applebloom asked her older sister.
"Not gonna force you to go" said Applejack "but it's a good opportunity for you to patch things up with Diamond Tiara!"
"Besides you 3 fillies will got me to keep you company" said Twilight "Harry came to the Library and invited me to the party, well his dad did but he was happy to let me go!"
"What's this Harry like?" asked Sweetie Belle.
"Well he's very nice, shy and he likes reading" said Twilight and she then blushed as she said the next bit "and he's kind of cute..."
"Does our Twilight have a crush on somepony" cooed Rarity playfully while Twilight responded with a glare.
Harry was flying in the clouds when a red Pegasus with a spire for a Cutie Mark went past him. Harry was then swirling out of control but the Pegasus caught him and helped him to land on a cloud in Cloudsdale.
"Okay there Harry pal?" asked the Pegasus.
"Just fine Vane" said Harry.
The Pegasus was Total Vane Harry's closest friend beside Silver Fork. When they were in Cheerilee's class Vane was among the group of bullies who picked on Harry and Fork for wearing glasses but he later apologised when they were older and the 3 became friends and Vane was even let in on the secret of Harry being an allicorn.
"your 1st true birthday party in less than a week" said Vane "and Fork told me you are getting along with Twilight Sparkle!"
Harry nodded and asked "you didn't invite anypony without telling me?"
"of course not" said Vane "I'm a different pony from when we were in class! So what have you been up to since it has been a while since we last hanged out?"
"I and Fork had a talk with our sisters about their bullying and I think it got through to them" said Harry.
"alright because I know I could have ended up badly if I hadn't grown out of the bully I had been" Vane said. Vane was of course referring to the rest of the group that had bullied Harry and Fork who stayed jerks and were now working as janitors in the Canterlot city hall.
"that's me going!" Harry said as he began flying home.
"if I don't see you soon I will see you at the party" said Vane.
"alright then Vane" said Harry.
