[Arcee and Rainbow Dash walk together]
Arcee: You ever get the feeling that somebody is talking about you?
Rainbow Dash: Kinda.
Arcee: Well, I've never been partnered with a talking horse.
Rainbow Dash: Really? That's awesome.
[Applejack and Bulkhead walk side by side]
Applejack: We should be there by now.

[At Autobot Outpost Omega One, Ratchet and Fluttershy are working on the goo from Arcee]
Ratchet: Sure is nice to have peace and quiet. Wouldn't you say, Fluttershy?
Fluttershy: Yes. Indeed it is. No nasty surprises or un-necessary jump-starts.
[They hear a noise and look around, startled. But there's nothing there]
[They turn around]
Ratchet: Optimus? [gasps] By the Allspark!

[The spider-like Terrorcon breaks the tool Ratchet was using]
Ratchet: I needed that!
[The spider-like Terrorcon gets ready to attack but is blasted by blue and purple blasts of magic and energy shot by Optimus and Twilight. It tries to get back up but Optimus steps on it.]
Ratchet: And stay broken.
Ratchet: Now what could have caused that?
Optimus Prime: I'm not sure. Twilight?
Twilight Sparkle: I'm not technically sure either. It was almost as it had been reanimated somehow.
Optimus Prime: I have a grave suspicion, guys. Dark Energon.
