Season 1 finale we did'nt see the resemblance which they indended for us to see. Even after Damon told us, I watched closely and could not see it, the faces were to dark. This time when the recapped that event, they must have chosen different footage or angles and it was clear; one had a moustache, the other did not but I could easily see it last night. They are being more clear about what they want us to "get" and I am really glad.
My impression on the injection, is that one of the things it does is make them super powerful. There may be other reasons for it, even to keep them alive due to health/medical issures. But unlike Qboots, I think he is one of the Others - he would have trouble paying his energy bills without their co-operation.
