Crush accidentally called me baby?

We were practicing for a community play, and I guess it was a slip of the tongue, but he said, "just try it again, baby." This was in response to me getting frustrated for messing up my line. He didn't retract his statement, though the shock on his face was pretty clear and he got red. We went on like normal after that. It wasn't awkward or weird. It just felt like nothing happened. There wasn't anything we could say about it in a room full of people.

Do you think this is a sign he's been thinking of us together? Or? He's been showing signs of liking me back these last couples months, and I think he does, but I don't want to overanalyze.
