I'm writing a story where one of the characters is taken in by three other characters, but they don't know the first character's name. I'm having a lot of trouble figuring out how to write this scene, since they can't refer to the first character by name.

(I know this scene looks rough, it's my first draft.)
They aren't going to know his name until at least two more chapters, and I have no idea what to refer to him as until then. How should I handle this?
