This is how Arcee and Rainbow Dash get on the Nemesis goes in episode 1 of season 2 of Ryan F-Freeman's Adventures of Transformers: Prime.
Knock Out: We'll be sure to tell the big O and T you said hello.
[Arcee and Rainbow Dash go after Knock Out and Breakdown]
Applejack: Rainbow Dash!
[Before the bridge closes, Arcee and Rainbow Dash race through it, leap over Knock Out and Breakdown's heads and onto the Nemesis]
Knock Out: Scrap.
Thomas: Arcee and Rainbow Dash. They must've noticed I was gone.
[Orion and Nightfall hear something]
Arcee: Where are Optimus and Twilight?
[Vehicon doesn't answer]
Rainbow Dash: ANSWER US!
[Vehicons appear and fire at them]
[Soundwave shows Megatron Arcee and Rainbow Dash on the Nemesis]
Airachnid: Arcee and Rainbow Dash. Allow me to welcome them aboard.
Megatron: No. If Orion and Nightfall so much as lay eyes on another Autobot and Pony let alone be allowed to witness their destruction, everything they currently believe will be called into question. See to it that Arcee and Rainbow Dash are escorted off this ship immediately!
[Orion and Nightfall see Vehicons firing at something]
Vehicon: Orion and Nightfall please return to your station. Lord Megatron's orders.
[Orion and Nightfall decide to investigate]
[Soundwave comes to a stop where Arcee and Rainbow Dash are coming, unaware Orion and Nightfall are coming down the hall behind him. Soundwave bridges Arcee and Rainbow Dash to the arctic just as Orion and Nightfall come up behind him.]
Orion Pax: We heard a commotion.
Nightfall Twinkle: Yep.
[Soundwave turns and sees Orion and Nightfall behind him]
Soundwave: [with Ryan's voice] It was just a false alarm.
[Arcee and Rainbow Dash arrive in the arctic]
