You might have missed Gwen's route? That's the last image.Be sure to re-check. Did you start over or did you use your save from episode 6?
Ohhh I somehow missed her route, I see now. Thanks!
Should I start over for the last picture in the gallery? I played through the events of Gwen's father and so on in the previous episode, chose to be with her, etc. Is that not fully her route? I continued btw with my old save.
I recommend to start over to make sure you haven't missed any route and points.
