A plot point that is presented to the player (initially) as "I'm not going to help you." I did note she got out of the way but also, the enemies weren't interested in her at all so she was useless as even a distraction. (Babysit was probably not the right word from a gameplay perspective but it's definitely how it felt to have her as a "partner".) At least the partners in RER1 pretended to be helpful, she literally would do nothing unless I directly controlled her and offered nothing except tedium in her gameplay. Like I said, I really enjoyed the first one but this game just felt off.
As an aside, I do not like the partner based gameplay Resident Evil has gone for and generally try and ignore it as much as possible. Fairly easy in 5,6 and RER1 not so much in this one.
