What had he been doing? How long had it been? Superboy had no clue what as going on, all he knew was that he had woken up only to find that a few weeks had past. He didn't know what had happened over the time and it wasn't as if he knew a lot about the place to begin with.
So he found himself again wandering the city, but this time with a purpose. Discovering what happened to him.
((Mainly an excuse for why he wasn't around for all this time. If anyone wants to fanagle an explanation IM me. I'm definitely interested in whatever CR I can get at this point.))
