If any party member is spotted by Madigan while exploring the barn without permission, the Fist orders them to go and speak with the Manip (which teleports the party to the entrance). Being caught the second time leads them to be arrested.
Rogue characters (only) have unique dialogue line while talking to Madigan, that can be used only the first time they are caught inside:
Rogue party member: This looked like the only place around here worth stealing from.
Using it brings the following approval/disapproval points from various companions:
Your attack summons thorny vines that possibly Ensnare your target.
Ensnared creatures cannot move and take 1d6Piercing damage at the start of each turn. An ally can use their Help action to try and tear away the vines.
