- who’s in the front, who’s in the middle, and who’s in the back
Pacce's in the front, since he's the leader. Hana's not far behind, and the haunted house was probably her idea. Taro's clinging to the back of Hana's shirt reflexively, whimpering and wishing he hadn't come along but he's not about to back out now.
- who acts like it’s not going to be a big deal but actually screams at the top of their lungs when someone in the group’s hand brushes their arm
Of the three, Pacce probably comes the closest, but honestly I'm pretty sure he'd handle it like a pro. Haunted houses ain't got nothin' on a former guardian! He still might jump if one of the others catches him by surprise, though.
- who’s scared about going in but they’re the only one who keeps their cool
As long as he's with his friends, I think Taro would manage to keep his cool - as much of his cool as he went in with, anyway.
- who keeps narrating their adventure in a deep voice as they wander through the haunted house
Pacce. Taro's grateful; it helps him know what's coming up ahead. Hana's annoyed because Pacce's ruining the fun.
- and, of course, who loses their shoe as they run out of the attraction
...Hana. She threw her shoe at one of the cast members.
