what if they're reintegrating her?
i noticed that the picture in the left corner of gemma's screen is similar to what it looked like when reghabi was reintegrating mark in episode three. if she turned her device on a stronger setting, the rings got closer to each other like in the picture of gemma. what if the reason gemma dies when finishing cold harbor is because she has would be reintegrated with so many different egos? (chikhai bardo, ego death... the two egos are fighting each other which results in death.) i think this could also be the reason mark has not been successfully and fully reintegrated, which a lot of people have been complaining about - because reintegration means death. and while people could argue "but milchick and cobel were discussing reintagration and he believed it's impossible while she also didn't appear to know for sure." - milchick is very probably out of the loop and cobel could've been pretending.
