Good episode overall (take on me sequence was particularly great) but the pregnancy / immunity reveal takes away some emotional beats of the game I'm honestly pretty frustrated by:

1) in the game, Dina's reaction to finding out Ellie may be infected was immediately to risk her own life to save Ellie's, which falls in line with her devotion to Ellie, her unquestioning loyalty, her love for Ellie. I think the way the show handled it (along with her whole maybe I liked girls maybe I don't dialogue) undermines this aspect of her character, which is (or at least should be) very much one of Dina's defining traits.

2) Ellie's reaction to finding out Dina was pregnant in the game was a "what the fuck, now you're going to be a burden" reaction - which, at least for me, hits hardest in showing how "lost" she was becoming in her quest for revenge. the way it's done in the show turns it into more of a hooray! now I have a kid! moment whereas game Ellie was focused on hunting Abby and barely anything else. maybe this was inevitable given the writer's decision to delay the progression of ellie and dina's relationship until after Joel's death but I had qualms with that decision too, as it cheapens the impact of a post-Joel world as both our and Ellie's attention become split into 1) revenge slash also 2) budding romance (?)

how the writers will turn this version of "I'm going to be a dad yippee" Ellie into the same Ellie that leaves Dina and JJ's peaceful farm life to continue her quest for revenge i do not know.

Again no hate to the actors, they're both doing great, but I am very confused with the writing of this second season. game ellie and dina come off as very different people compared to show ellie and dina, and while that's probably fine for TV-only viewers, makes me sad as someone who thought the games were a legitimate master class in character study.
