This episode was ok. I'm sure G'iah will be back, it would be pretty unbelievable if they were to essentially fridge another female character after Talos's wife and Maria Hill. Or maybe she's dead and Fury's girlfriend is next lol.
Tonally it's an odd bird. It's trying to telegraph importance through hints at real-world issues and themes, but it doesn't have the time or interest to delve into any of them, so far. At least to me, the few attempts at levity have come across as a bit awkward. Talos and Fury are supposed to have this almost brotherly banter, but there's something unrehearsed about it and I'm not entirely buying it, even though these actors are the best of the best. Maybe it just would have been nice to see more of it beforehand and now it would feel more emotional.
Secret Invasion has enough easter eggs for any Marvel fan to stay awake through these episodes, but I really don't know how I could sell this to a more casual fan. None of my friends are watching this show, except for the one super fan who isn't completely jaded by Marvel by now and she isn't exactly loving it either. Take the MCU context out and what we have left is a run-of-the-mill, regrettably boring sci-fi show with a shoestring budget.
