Everybody I met (John Simm, Jewel Staite & Bernard Cribbins) was lovely but I just wanted to add a special mention for Gates McFadden. Admittedly her queue was non-existent at the time but she told my boyfriend he had a lovely smile and spent quite a while talking to us/him. She actually managed to seem genuinely interested too, asked where we were from, from we did, what my boyfriend wants to do with his Biomedical Science degree (and pointing out that he could be 'another Dr') etc.
