I've played through this game many times using Wesp's patches, and pretty much all times I've helped the Voerman sisters put aside their differences. This time, however, the dialogue ends with one or the other killing her companion and I'm left with 1 XP less. And I even have 5 in Persuation.

To reconcile both sisters you need to be nice to them all the time. The other option was something not in the original game that looked good back then but didn't made sense in the end.
