This show has always required time to unfold. It has always been pretty far out there, as well, so I don't understand the surprise at its form. Personally, I'm riveted because the tiny details can make a big difference in understanding.
I'm glad to see they found a way to bring Ptonomy back. Last season, it seemed like they'd forgotten about him, so, I'm glad they haven't. (Speaking of last season, it played much better on re-watch without a week's delay between episodes.)
No Melanie this episode. I hope we're going to see her coherent and involved this season.
The team sided with Farouk because they believe David will destroy the world, and Farouk is supposedly the only one who can stop him. Cary realized that, at some point in the future, he built that sphere/drone thing and sent it back to capture David (at the end of Season 1). Because of that, he assumed - and convinced the others - that David must have done something truly terrible that warranted capture. When he then saw David manipulate Syd (wiping her memory), he jumped right to "treachery" and mobilized everyone. By putting David on trial, they ensured that he would turn against them. Trusting Farouk made little sense, even so. (Especially now that they simply went in with a tactical team and Syd shot him. I'd guess that they needed Farouk to locate David, though he admits having trouble doing so.)
David didn't sense the team coming because Cary gave them headbands to block their brain waves so that David couldn't tune in. He can handle them, as we saw twice when he disintegrated them all. Except Syd, who shot him. Not sure why she got through.
Don't know yet why he needs a time traveler, unless some future version of himself put out the call, knowing after the fact what would happen and needing her so he could even get to that point. I loved that he moved the whole facility. Take that, you betraying idiots.
What I find interesting so far is that the team expects an explosive, reactive David, and yet he has created a rather 60s-ish commune and seems quite peaceful. And, he's still talking about needing love. End of last season, he kept saying how he deserved love (it's the reason he manipulated Syd - wrong though it was), and so that's what he created, for himself, with no apparent need for retaliation against his former friends. That we've seen. Yet. Actually, they're the explosive, reactive ones, working within their own self-created loop.
Still much to unfold, I'm sure.
