We never got a explantion of were he was at the whole time. I know he was trying to be hunted by Cemintary Wind like the other original's but it's not so clear on were he was at.
What exactly do you mean? He was obviously in hiding. Apparently, he was with Leadfoot if that alleged deleted scene is anything to go by.
I'm guessing no explanation was needed as most people would infer that he'd been on the run from the humans the same as the rest of the Autobots. It ain't rocket surgery
Deleted scene? I don't remember a deleted scene besides the whole "dance dance transformation" thing. That's what i saw in the movie.
