Yeah, I wonder. Might be fun to try a different shade of green on him. And his friends could be green too! That'd be funny.

It is very likely that Stella might say something awkward or inappropriate, but she generally talks about her research in a vague scientific way until she gets down to business. And she is very careful about who she's dealing with, but it might come up. Yeah, it might be hard to embarrass Ripp, but he does seem a little evasive about the alien thing, doesn't he?

Ripp will definitely be sober(ish) at dinner, since he's with Johnny and Phi. The drinking will happen at the second party, so aside from maybe a bit of bubble blowing... and maybe not even that.

Yeah, it's all about genetics with Johnny and Jayne's marriage. Maybe I didn't explain it well enough in the Stella chapter, but they essentially consider the hybrids a new species, and want to maintain it. Breeding with Ophelia would dilute Johnny's genetics to an unacceptable level in the eyes of the aliens.

Stella is careful about how much she tells to which people. Ripp got informed about some of it because he was going to find out anyway. :P
