I asked for mixed; mixed fandoms and mixed gender.
amatara gave me Eowyn from LOTR, Mickey from the new Doctor Who, Dr. Leonard McCoy from Star Trek (TOS), and Susan Ivanova from Babylon 5.
The 'cliff' aspect was a little easy, cause Mickey's not one of my favorite characters. While I find him attractive, he's also a tad desperate and whines after Rose so much it would be very annoying to be around him. I'm afraid it's the cliff for you, fella. (Note: I slipped him a parachute. I still like him. He has a nice relationship with Jackie, and he was kind to his grandmother.)
I thought about marriage next. See, I have pretty strict criteria for marriageability (having a pretty nifty marriage in RL.) I eliminated Susan pretty quickly. I love her, but she's not ready for a serious relationship (IMHO). Maybe a few years after Sleeping in Light, but not during the series. And while my ten year old self squee'd at the thought of being Mrs. Bones, I really don't like driven men as mates. Leonard would put his patients ahead of me, which would be the right thing to do, but I wouldn't like it. That left Eowyn.
The more I thought about it, the more I liked it. She's strong, and caring, practical but with a high-flown sense of romance, and an intense sense of responsibility. She's also capable of running a large estate all by herself. She'd teach swordcraft to my boys, and we'd have a big place with horses and a ginormous garden. I started to picture long winter evenings in the Great Hall, mulled wine and a big fire in the fireplace...planning the improvements to the smallholdings under our care, and preparing for the spring planting. Anyway, I've sold myself on the idea. I'd marry Eowyn.
Snogging and shagging. This was really, really hard. Boy, if you'd asked me pre-B5, it would have been McCoy all the way...with going all the way. Those eyes...*melt* But you know, I think I'd be good for Susan. She needs someone to show her a good time without any angst or tragedy. Sex can be mind-blowing, and deeply spiritual, but it's also a helluva lot of fun. She needs some of that. And of course it doesn't hurt that she's drop-dead gorgeous. And sexy, and amusing, and sweet, and oh so sad. Okay, for her own good, I'll pick Susan to shag. Hopefully I'll teach her why good sex always makes me laugh.
Leonard, I'll kiss, with all the fervor of my younger self, and all the deep appreciation of my older self. I want him to understand how much he's meant to me over the years. He taught me what dedication and devotion to duty meant, as well as friendship that never wavers, and a cranky belief in the essential honesty of human emotions, both good and bad. He sent me into the sciences, but never let me forget that service to humanity is the reason behind the figures and graphs, the numbers and charts. The only caveat is that I want to do it in full view of Captain Kirk and the crew. The man is grossly underappreciated, and I'd like to march up to him on the bridge and indulge in a long leisurely snog. Then I'll leave without a word, only a whispered 'thank you' that only he will hear. The rest of them can enjoy what I hope will be his pleased and triumphant grin.
