Choice three
We have a bathhouse on the property at home, so investigating the one here makes sense, I guess.
The locker room area is filled with rows of small insets, filled with robes and different types of clothes. It's all fairly standard, although bigger than ours, I guess on account of the number of people present.
With the locker area mapped-out in my head, I move into the bath area. As I step toward the door, it suddenly opens and I'm thrown forward violently. Rolling forward to avoid crashing to the ground, I find myself in the bath area.
Inside, I find Rider, Arc, Leysritt, Nero, Kohaku and the lady pirate Drake all bathing, naked.
Well crap, what to do now?
1) Run, you fool.
2) Calmly join them.
3) Apologize and leave quietly.
