Well as "Smallville" is winding up for a close as all know, it's only a matter of time before Clark begins to fly. I believe it could be in the episode titled "Icarus." This is because in Greek mythology a man named "Icarus" created his own wings and could fly. I have no source only my own theory and as the producers have said that this episode is filled with surprises. It may also feature Clark and Lois getting engaged.
Well tell me what you think below!
