You saw Terzo looking for something in the small storage closet and was curious on what he was looking for and joined him in the tight space hugging him from behind

Terzo jumps when you suddenly hug him but relaxes when he sees it's you. You him hugging him while he was searching in the storage closet when two ghouls chasing each other bumped into the door closing it and locking you and Terzo inside

*You collide into Terzo and he holds you while shouting "Who closed the door?! Let us out!"
