Stargate SG-1; Season 7, episodes 17-18 -- Heroes

So, I'm finally watching the end of season seven of Stargate: SG-1 (probably because of reading about the renewal -- I'd sorta been holding the second half of the season 'in reserve' because I didn't want the viewing experience to end. Happily, this is no longer a problem for this season. Yay for season nine!).
