Telepathy
So helpful when I have so many sci-fi/fantasy fandoms, that this will always pop up. Telepathy allows for undying attraction/love to be said without it really being said in awful mushy ways. Also leads to a good lot of funny moments, and nicities of having one character being able to explore another in a way that we as writers do (getting insider their heads to understand them).
There's a few Telepathy fics in the SG1 side of things (
Reveille is the best of them). And I've just come across one for Metal Gear Solid. Which again only leaves me to wonder why I have yet to come across one for Man from UNCLE. Come on. An interrogation with a mind-reading device goes wrong, and now Illya and Napoleon can read each other's thoughts? It could be amazing! Maybe it does exist, and I just haven't found it yet.
Also was one of the first things that appealed to me about Sapphire & Steel. Though they cannot actually read each other's thoughts, they do communicate telepathically. Which automatically made me believe they must do brain-sex all the time.
Hypothermia
Character 1: We're uh...naked
Character 2: Yeah, you had hypothermia, so I had to keep you warm so that you know, you'd be alive.
Character 1: Oh, I see. Well, thank you.
Character 2: I guess this is awkward, what with our pre-existing sexual tension and all.
Character 1: ...yeeeeah.
Character 2: Rather convenient then, don't you think. Us, naked and under blankets, and you all grateful for me having saved your life.
Character 1: I suppose we'd be dumb to waste the opportunity...
Character 2: Yeah... ooooh...
Character 1: Oh! hmm.. mmmm...
THEN THEY DID SEX!
It's so cheap. But God, I love it. I have gotten this with Jack/Daniel, Jayne/Simon, Napoleon/Illya, and Snake/Otacon, just to name a few. Though if I recall correctly this scenario actually played out in that movie of The Saint with Val Kilmer having to warm up the lady after she fell into some water.
