What happened to him? After explaining about Megatron and Galvatron, he plucks a flower and says "It's your problem now" (something like that) and then the camera cuts to Optimus and we literally never see him again.
after surviving a ship crash & then immediately being tortured every day for the past 4 years..this was a changed-brains...i think he pretty much said 'F this im taking the rest of the movie off, you guys handle it.'
Well he had a lot on his plate first he probably went to get a haircut cause that shit was all in his eyes and stuff. Then at some point he had to get that leg looked at plus therapy for all the emotional trauma of being locked in a box and forced to interpret the rantings of a mad man. I'm gonna say he was busy enough. It would have been classic to watch him interact with the Dinos though.
I never felt for Brains in DOTM and didn't care that he was possibly dead, but now, I kind of wish he would have joined Wheelie in the well of Allsparks. It bothered me a lot to see Brains in that condition, walking around in struts and being fried. I'm pretty sure he gave up on the Autobot cause after being rescued.
I simply assumed he didn't want to get involved with this battle. I mean, last time he did he lost his best friend and got captured. That, and its not like he'll be a help in the fight. So I just assumed he stayed in the ship or even just left.
He most likely said to Optimus he was going to stay there in the garden, And to come pick him up if the Autobots left Earth.
I'm guessing he set out on a journey across the world to find wheelie. Finding wheelie. Spin off anyone?
that'd be awesome...i thought their interactions in 3 was 1 of the better parts of that film...how about when brains was riding wheelie in alt mode in merling's office? too cute!
