To 1: Good to know. I mean, in the early game it makes sense when Catherine is deeply indebted and lives a "normal" life. It just doesn't make sense as soon as she's recruited by the Emperor^^
To 2 and 3: I see, then it ended like that because I played the romance scene with Seralli before (she's too cute, how could I say no?) So the scene I meant, with Evelyn and Jeanne, will be tied to Evelyn's romance route.
To 4: If it's too difficult to do, then it's too difficult. But thanks for looking into it :3
