So. Umm.
a) very nice Married Couple Husbands Supporting Husbands vibe. I think it's good that they've moved on from tension-laden eyesex to casual intimacy, trust, and simply being there for each other?
b) Dean refused to trust Lily because she tried to kill Cas, simply unforgivable in his book.
c) The Empty once said to Cas, "I know who you love." And now is pulling a BTVS "when you experience one moment of perfect happiness" thing? is there any being in the entire universe that doesn't ship it? that said are we finally going to get a kiss and then Cas will drop dead? does the Empty honestly believe Dean Winchester will not tear the universe apart to its component subatomic particles while demanding to know "Where's the angel????" if that happens?
