1. Jareth, from Jim Henson's Labyrinth. He's my biggest crush.
2. The Doctor, either the 10th or the 4th. Although I'd prefer the 10th. Brilliant, a little wild, and a loyal friend.
3. Elrond, from LOTR. I'd probably end up asking him to adopt me. Whenever my real dad is being . . . well, I won't get into that, but sometimes I close my eyes and imagine what it would be like having Elrond for a father instead, and it helps. I even tried to send a letter to Hugo Weaving thanking him for that, but I got the address wrong and it came back unopened. Oh well.
4 and 5. Samantha Carter and Ba'al, from Stargate SG1. I love the interactions between those two. Their enemies, but when they work together they're almost friends. And Ba'al is hot.
