First things first, I haven't read much of the 1602 universe in the comics, so I have no idea how much of it they've borrowed for this. Although I DO know that Stark is some kind of powerful, popular, respected knight in the books, where he's not that here. Anyway...
The writers have done really well in showing how much Captain Carter is like Captain America in the 616 universe. It just further cements that they're a pretty iconic MCU couple.
Much like the previous 2 episodes, though, it really would have been nice if we could have got a bit more of this, though? Surely with streaming having done away with the need to rely on adverts and designated time slots, they could run these episodes longer than 20ish minutes when necessary? By that same token, though, there was a little bit too much 'filler' here, but that could also have been used better with more time for the story to breathe.
Like I said, though, it's not the strongest episode this season, but it's still (mostly) a good one, if a little too short and rushed.
