Logan was crippled in S1 but they found a guy who had this (if I remember correctly) framwork thing for his legs that enhanced them. Logan got his hands on it and uses it to walk. I think there was also a point where he used Max's super blood to reverse the damage to his spine but that only worked short term.

Yeah, Max stays with Logan but there are a few points where it looks like she and Alec are getting cozy. =) I was told (dunno know accurate it is) that the producers or something wanted Alec and Max to hook up but in rl the actors playing Max and Logan were engaged (or married?). The actor who played Logan had a hissy and that's why season 3 got scrapped. =(
