I'm mostly talking about the meaningful routes - Mikko's and Torulf's, since they are the big branching ones with a lot of deep character exploration, while other routes are more straightforward.
In Torulf's route she inserts herself at the point where I simply don't believe Arvo would let in another pushy stranger and it ruins my suspense of disbelief.
In Mikko's route she comes in at the exact point where Arvo can salvage things and talk to Mikko straight, with the fire of Mikko's decisiveness lit under the tiger's ass, but now it's suddenly a group outing and he doesn't get a moment of intimacy because of her. It's frustrating to the highest degree.
Fuck her, she ruins everything, both times coming in at the worst time with the worst opinions, without anyone asking her. She is a really obnoxious person, in my opinion.
p.s. also she's being a possessive friend in Jorgen's route early on, but I haven't played Jorgen's route for several updates, so idk what she does there yet.
