If the guided join you in Episode 2 on the Marna Stretch Jeng will start out with maximum XL for the first combat when they are in your party.
The next one is in the pits of Episode 3 right before the plunge against the shadow man. If you avoid the risers and go back to fight them after Scatha leaves the party, Scatha will still be mentioned in some of the messages during combat ("Rhue and Scatha are burning up."). This may not even be worth doing anything with, but I thought Lun should know anyway.
This is probably nothing. I just want to see what Lun has to say about it when he gets a chance to read this.
