My only real issue after seeing the trailer is, although I know she actually is in her early 20's, I feel like she still looks too young as TLOU2 Ellie, knowing what the events of the season are going to be. TLOU2 Ellie and kid-Ellie from season 1 are very, very different characters with the very different roles.
For Abbie on the other hand, while I would say game-Abbie is a touch TOO hench, I wonder about TV Abbie not being hench enough? There's a parallel supposed to be drawn between the characters in that they can very much take care of themselves; Ellie because she's been raised by Joel and has a tonne of skills/smarts and Abbie because, frankly, the girl is an absolute tank - there are parts of the game where you can straight up have her kill Clickers with her bare hands
.
Looking at the two of them in the trailer I'm not sure you get that contrast of Ellie being quick/smart/"tricky" and Abbie being hard as nails.
