How sad is it that I squeed at the light switch? Hee! And I loved the continuity as well - the missing jumper, Kanaan, the baby (who was taking care of him during the crisis?), Carter in isolation, a mention of Weir, iratus bugs, turning into a bug, the retrovirus to cure the hybrids (finally a good use!).

And I thought Woolsey was perfect!

Don't get me started on the Shep whump. I'll be here all night.
