RE: your Deadlock spoiler - no they didn't, you're thinking about "Scorpion".
I don't know why you're hyping up "Dreadnought", its nothing to shout from the hills about. "Deadlock", "The Thaw", "Tuvix" and "Lifesigns" are season 2's highlights, no offense but you have bad taste. Resolutions as a 2 part finale!?
Anyway, its best not to set up any expectations for admiralscreed for future episodes, I'm sure he'd prefer to enter into them without having any, any episode is more enjoyable that way!
