My party entered the temple of Titan, got shot at by some monks, shot them dead, and defused some alarms. The first interesting thing we found was a guy who makes a "muffled shouting" noise. Presumably he is in a straitjacket.
I tried "converse" and I couldn't interact.
Recalling that sometimes "Surgery" was necessary to free people trapped by vines, I tried surgery and couldn't do it. I tried lockpick and it said "not a valid target."
I don't have any party members with "brute force" skill, or I would try that.
Possibly there is no way to interact with this character at this time. (I wonder why the game didn't give some clues as to why I can't interact.) Should I continue trying to interact, should I explore the rest of the temple first, or should I just leave the temple, wander away, and forget about it?
