That was cool seeing all of them in their former lives. Yeah, it was a slower-paced episode, but I liked having the breather and getting a moment to think about things before the next big thing happened on screen. Some really cool scenes, though. I liked Loki going to that room, seeing himself reading a book or something, saying "Hello", then slipping back and entering the room again, but this time he's not there, so he wanders over, sees the book, picks it up, and we realize it's the same scene from 20 seconds ago but from the "other" Loki's point of view, then he shows up and says "Hello" again and disappears again. Time paradox stuff is fun. Kinda like seeing him get pruned by himself last episode, the other side of that same scene from Episode 1.
So if Casey (or Frank, as he still thinks of himself) didn't steal the TemPad at the end, who did? That didn't get answered because they all started going spaghetti, then Loki realized he could control the time-slipping. One of those things that got tossed out there to probably be revisited later, but instead we quickly moved on to something else. There were thankfully only a few of those this time.
Frank was one of the three inmates who escaped from Alcatraz in 1962. I liked how Doug's lab in the "real" world looked basically the same as O.B.'s in the TVA. Don was the Jet Ski salesman who became Mobius; we figured it had to be something like that. I liked how B-15 was Dr. Willis. They all came from very different walks of life, which I guess makes me wonder how each of them was "chosen" to be in the TVA. A question for another time, I suppose. Why did Sylvie remember both her present and her past, when none of the others did? She kinda explained it quickly, but I didn't really grok it in fullness. Because she, like Loki, is sort of "outside" of all the timey-wimey stuff?
