This is how Bridging out goes in Darkness Rising Part 3.
Optimus Prime: This substance had the same affect on this device as it had on Cliffjumper.
Ratchet: That would explain his life signal coming back online, but Dark Energon. It's so scarce seems to be virtually non-existent. What would it be doing in Equestria?
Optimus Prime: I think Megatron may be using it to raise a horde of undead Terrorcons to conquer Equestria with.
Ratchet: True. Very true.
Twilight Sparkle: We need to figure this out.
[Autobots and Ponies arrive]
Rainbow Dash: Hey! Guess who's back!
Pinkie Pie: Alright.
Smokescreen: Nice prank, Pinkster.
Rarity: That was fabulous.
Bumblebee: [beeps] (translation: I know.)
Applejack: Miss us, Doc Bot.
Bulkhead: His name's Ratchet.
Optimus Prime: Autobots, prepare to...
Arcee: Roll out?
Optimus Prime: Remain here
Twilight Sparkle: We have to find out what Megatron's plan for this substance's use is.
Optimus Prime: Your decision is wise, Twilight. Ratchet, we may need your help.
Ratchet: But what about Fluttershy? I can't leave her here on her own.
Optimus Prime: Then she will tag along.
Fluttershy: Okay. But I don't want to get hurt.
Optimus Prime: Arcee, you're in charge.
Arcee: Optimus. Playing bodyguard is one thing. Baby-sitting is another. And besides, Ratchet hasn't been in the field since the war.
Optimus Prime: We know.
Twilight Sparkle: Can we just go?
Fluttershy: Come on.
[They enter the Groundbridge and it closes behind them]
Rainbow Dash: So, what's on the activities list?
Arcee: You stay here.
Arcee: When you're in charge, you need to handle the girls. Bee, with me.
Bumblebee: [beeps] (translation: Aw, man. Bye girls.)
Arcee: Bulkhead, Smokescreen, you're in charge.
[Bee and Cee transform and leave. Bulkhead and Smokescreen turn to the ponies]
Bulkhead: So, uh...
Smokescreen: What's on the activities list?
Applejack: [plugs a bass into a speaker] How about a song? It's called Awesome As I Wanna Be.
[She starts playing and the song begins]
Awesome as I wanna be~
Smokescreen: Hang on! Stop!
Rainbow Dash: What now?
[Alarm goes off]
Smokescreen: [points] Proximity sensor.
Bulkhead: Quick, hide!
