How long do you think it will be before it comes up? If it really is tied in with Exodus, I'd be surprised if they didnt mention it at some point-maybe in season 2 when they're supposedly going to tell us about BBs voice (cant remember where i heard that though...)
IIRC, Ratchet has used "By the Allspark" in regards to certain things. Can't remember exactly what, though.
Ah, I gotcha. I wouldn't be surprised to see it in flashback when we learn about Bumblebees voice. Losing his voice was Megatrons "reward" for firing it into space.
i remember he used it when dark energon infected a broken tool or something...in darkness rising i guess...
