But but.......she took on a giant man in hand to hand combat and choked him out.

One kick to the stomach from the small mexican dude took her outta commission lol.
Bingo. Seems like some would rather have a big muscle bound chick that cant act playing abby to be "faithful to the material" than someone that can act. With how stuff played out in the show, it seems her muscles werent even necessary.
I dont think it was Neil caving, it was probably Mazin, he the showrunner/running shyt. Has the tv experience and probably felt they had to do it this way. I didnt play the game, but the show audience would get annoyed with seeing Abby's pov for 3 episodes for extended amounts of w/o knowing her motives imo.
Spoiler tag it if need be, but how did she know she had the right Joel if she didnt talk to him about why she was doing it?
