Yeah, the last two episodes have been pretty fantastic.
Though I have to admit (highlight for spoilers), I'll be pretty disappointed if Jason Isaacs (Lorca) is gone for good, as he's been one of my favourite parts of the show. I guess the door is open for him to come back---Stamets did mention in the previous episode that nothing in the spore network is gone for good, so maybe Mirror Lorca getting dropped in there didn't kill him for good. Or there's also the possibility that the Prime Universe version of Lorca might show up at some point. I also assume that, with the crew having jumped nine months forward to a future where the Klingons conquered Starfleet, there's some more time travel hijinks to come, which could be another vehicle for bringing back people assumed to be dead.
