Xen stands, seeing Ruby and Holli have their fun and blushes, clutching their shirt to themselves wistfully. They give Killjoy their satchel and say "Here...I trust you to give me a fair share of the loot. I gotta take a breather...I'll meet you guys in the vault." Xen makes their way to the shaft and climbs up - careful not to slip - and ends up at the top. In their alone time they keep watch, though also make an effort to pace around the entrance chamber, whining to themselves.
