No -- no, I'm not from the past. Same time, actually. It's...complicated.

It has to do with quantum mechanics. I didn't really get a chance to go over all the details in full, but from what I understand, something happened when we took off from Cybertron in the Lost Light. The problem with the quantum engines made it so that there were two Lost Lights -- and technically, they're both the original. One of them wound up where we were supposed to be going -- that's the one I was -- and the other went...somewhere way, way off course, I guess.
