What was the first initial of your TA, I can put you in touch with him or her :D
Not OP but he was my TA too and I think she capitalized babe for more reasons then one. I agree with OP btw what a total Babe!
1a is right, that's him. I'm too shy to email him. I'd be grateful if you could put in touch with him :)
Are we talking blue eyes, impossibly well-dressed, and walks into a room like he owns the place? Cuz if so, Babe indeed!
