Have expressed my general thoughts on the ep elsewhere (I liked it well enough - not a great ep but a good one) but something else has just occured to me:

With all the "Teyla missing/Carson back from the dead" stuff going on, everyone seems to have completely forgotten the rather important issue from Part I of the nasty Hoffan virus Mark II being used to randomly infect worlds and kill rather a lot of innocent folks in the process. What with dat?!!

I, like you, am utterly unspoiled for the finale, other than the general bits I knew of months ago, and am hoping to stay that way and let it all be a surprise. :)
