fannish curiosity (killed the cat)

Mmm, coffee. *takes another sips* So, someone on my flist (I'm being vague because it's a locked post) posted about forgeting about being besotted with RayK when she hadn't watched due South in a while. And I was wondering, which characters do y'all feel like that about? I obviously have lots (Methos! Susan Ivanova! RayK! Utena! John Sheppard!), but if you had to narrow it down to one or two, which ones would you choose? And what especially do you love about them?
