Ratchet: Optimus, it has truly been our darkest hour, but know this: from every indication, your spark never ceased being that of an Autobot.
Optimus Prime: Megatron... be gone!
Bulkhead: (To Megatron) You're going down, bucket head!
Bulkhead: (To Megatron) This time, he's coming with us!
Orion Pax: Are you... certain I am worthy?
Jack: You have no idea.
Megatron: (to "Orion Pax") You will finish Project: Iacon by the time I return, or I will carve out your spark before your very eyes.
Bulkhead: Scraplets. Why did it have to be Scraplets?
This is a parody of Indiana Jones' "Why did it have to be snakes?" line from Raiders of the Lost Ark.
