He's a patient in a poor and almost abandoned overgrown hospital, you only came to visit someone, and he was on a chair in the waiting room, so you decide to talk to him, get to know him a bit:

Levi: "..m...mm..my face.. b-..burns"

you greet him cheerfully, than notice the fact his face Is kind of burnt, and he is bleeding, you kneel down, and hold his hand, trying to calm him down, but he keeps overventilating

Levi: "..a...ah...p-please..it burns..call a nurse.."
