Definitely will need a walkthrough in the future...even now could use one.
Having the choice to either confront the Baron & Isabella yourself or let Tristan do it for you, I now have 2 different saves cause I don't know which route is better.
If you do it, you have the chance to be honest and pray she trusts you enough.
If your brother does it, he will lie for you, which will save you temporarily but may end up biting you in the ass down the road cause then you will have let your brother lie for you.
It'd definitely be good to know which path leads where, cause I really don't want mu;tiple saves of confusion on this game. lol
