Been thinking about the whole supergirl thing and how she can fly and clark doesnt know he can do it yet.

Surely when he meets her and sees she can fly it would make him think,well maybe i can do that too.

always remember the episode where he woke up and was floating at his ceiling and never mentioned again. when he started to develop other powers he tried to develop them fully but this was just ignored.

why are they not doing it yet?

Good question sheva lol. But I do believe that in that very same episode Jonathen says to clark some thing along the lines of Your powers are amazing son but "when you start to defy gravity, I thin it goes way beyond any thign of our knowledge" some thing along the lines of that. Any way I think the answer you are looking for sheva is that in smallville the writers purposefully gave clark a fear of heights as a way of preventing him from ever flying soon. This in turn was perhaps the reason why they thought they could just shrug the whole flying power off until later when there was no running away from it and I have to say it has worked until know but you are right, clark now knows he can fly and perhaps they might give us a small glimse of it towards the very end of the series.

I think they will leave clark flying to the last minuet, I mean they gave him supperbreath in seson 6, which was about time as he didn't devolop any new powers in either season 4 or 5.

All i can say is it is about damn time that he can freeze people lol.

Yeah it would be sweat if he froze lex and just left him like that.
