She’s literally constantly restraining herself from murdering everyone. Like going on a brutal beast like rampage.
The rest of the time she’s like a genuine stick in the mud who literally doesn’t understand jokes or fun. No sense of humor. Doesn’t care about literally anything other than missions. Seeing everything else as a waste of time, and actively pushing most people away out of fear for what she will do…
Not fixable in current state. You could prove get her to listen while you talk. Maybe full her into getting a handy or something idk lol
