I've been to quite a few cons now and I notice that some guests leap onto the stage and go straight into the Trek related anecdotes. And some don't. In Melbourne she immediately opened it up to questions so what got discussed really depended on what questions were asked. She was happy to talk about 7 though, unlike one guest I heard who seemed to think it ridiculous people were asking about his Trek character.
I had a couple questions but other people asked similar so I didn't end up asking anything.
It's true she wasn't at all the entertainer like other guests, but she was lovely in her own way. Just personality I thought. She got quite warmed up talking about 7's character as well as the costumes.
