Well, I have to confess that it took me 3/4 of the episode to realize "hey, this isn't Arctic, this is Quest" and that realization mostly came because I realized there was no way they had time for Lex and Clark to get up to the Arctic, much less have a pivotal confrontation scene, and have Lana's goodbye to Clark, etc. (Apparently season 7 just isn't sticking in my brain as much as earlier seasons).

Still, you would think the network could remember which show was actually the finale!!!
