We won't know why Ozpin is acting weird until later chapters, since the best hint we got was Ruby's words, 'it's as if he wasn't even there.' That's practically useless until we can specify whether he's just occupied in the mind, or something more substantial.

And Glynda very likely is the deputy headmaster (or headmistress?), I mean, it felt that way from the very beginning. Whatever Glynda might think (or her official position), Ozpin clearly treated her as an equal in many matters.
