Twilight: Don't leave I need free labor.
Rarity: Don't go, I need a sucker for my store and too con you off any jewels you get.
(Yeah, nice save kid, )
Two friends are enough, then He's pitiful then I thought.
Twilight: I need to keep this one little privilege, please don't leave!
Twilight, just stop, you have Starlight and your pet owl to help you, just let Spike be with his own kind.
(The only use for Rarity is if it's Spike realizing, "Wow, the more I think about it, she's waasaaaay to old for me")
No, Sparity is still creepy(and so are the shippers, have you seen the drawings?
Two ponies are no reason to not leave and join your own people. Two isn't enough, it's far from it.
Spike, sooner, or latter, it will be time to come home.
A dragon must have ability to rely on themselves when needed, and must eventually horde
And before you say
"But Twilight said he's as much apart of his family as anypony."
1. That's speciesist
2. But he's NOT a pony.
and another thing(aside from Twilight and Celestia(his adopted mom) he will outlive all his friends.
Dragons live hundreds to thousands of years! Think about that for just a second. He is only 10 years old(maybe older now) but the point remains, his best years are still to come, where as the Mane 6, sorry, but their best years will soon be behind them before they become old and die(sorry everything dies, some sooner then others)
And Rarity had NO right to try and talk him out of leaving(Twilight does, and Celestia does) but not her. If she did care for him, she would encourage him to go so he can finally have a parent. Not that some snobby mare like her could understand.
hopefully this dragon points out and shames him for having a creepy crush on Rarity(Really son? REALLY!?) which would be awesomesause!
What the heck is he supposed to do when he becomes a GIANT?! And can crush a pony with his pinkie claw?!
Twilight has been a good sister figure, but I repeat and until you give a detailed, good explanation about why he should stay after that, then I'm sorry, he needs to GO!
And if it's the same bs lines from Dragon Quest, I hope the writer gets trolled into oblivion(4Chan style)
"Birds of a feather must flock together"
The best ending I can see is a tearful goodbye, like that fan animation about Twilight(being an actual good pony and letting Spike return to his people) he's not going to fit in the castle once he grows to Torch's size.
There, I think I made my point.
Two privileged friends are not enough. Those two could never understand what it's like to not have parents.
Check and Mate!
