This is how The Autobots and Mane Six reunite goes in My Little Pony Transformers: Dark of the Moon.
[We see Twilight, her friends, and the Autobots talking]
Twilight Sparkle: It's been a while.
Optimus Prime: Indeed it has.
Rainbow Dash: How's it kicking, Ironhide?
Ironhide: All good.
Pinkie Pie: Jazz! Good to see you again!
Jazz: Good to see you again, Pinkie.
Rarity: I haven't seen you in a long time, Bumblebee.
Bumblebee: Neither have I since the Fallen's defeat.
Applejack: Hey, Sideswipe! How's it been hunting Decepticons?
Sideswipe: All good, Applejack. [hands Applejack an apple which she eats]
Fluttershy: Hope you've been showing lots of kindness to your patients, Ratchet.
Ratchet: I always have.
Major Malfunction: It is good to be back.
Optimus Prime: Girls, I like you to meet some new friends of mine. This is Dino, Que, Roadbuster, Topspin, and Leadfoot.
[Rarity and Bumblebee talk]
Rarity: Are you sure you can't stay long?
Bumblebee: Come on... Rarity.
Rarity: I know your black ops stuff is important. You know I'm not trying to diminish it, or guilt trip you, or anything. But I just never see you anymore. You can't come to my boutique and stay on one night?
Bumblebee: Rarity, that makes me feel bad.
Rarity: But will we still see each other?
Bumblebee: Rarity, you are the one pony I care most about. If there's anything you need, I won't be far.
Rarity: I know that. But sometimes we all need company from someone.
Bumblebee: There are some things we just can't change.
Rarity: I honestly take that for granted. But that's not...
Bumblebee: We've got to stick together.
Rarity: That's the reason why I am asking to stay here with me.
[Bumblebee looks shocked]
Rarity: Please, Bumblebee. It's only for a while.
Rarity: So what do you say? [holds out her hoof]
[Bumblebee turns to Optimus]
Bumblebee: Permission to speak sir?
Optimus Prime: Permission granted.
Bumblebee: I wish to stay with Rarity.
Optimus Prime: If that is your wish.
[Bumblebee grins and accepts Rarity's hoof]
Bumblebee: Then its settled, Rarity. I will stay with you.
Rarity: Thanks, darling. And I'm sure my little sister, Sweetie Belle, would like to meet you.
[At Rarity's Boutique]
Rarity: Welcome to your new home.
Bumblebee: Sure is nice.
[Sweetie Belle comes out]
Sweetie Belle: Who's that, Rarity?
Rarity: Sweetie Belle, this is Autobot Scout Bumblebee.
Bumblebee: Uh, hi.
Sweetie Belle: Hi.
