Big surprise ;D I've chosen Bill/Laura

Here comes my list (in no order):

#1 their relationship develops slowly and naturally
#2 they both care about books & literature
#3 the reading sessions in sick bay
#4 they show their love in so many (small) gestures
#5 the actors (I love Mary, but Eddie even more!)
#6 the natural chemistry between them
#7 after a heavy start they respect each others decisions
#8 how they look (together)
#9 them in "Unfinished Business" extended episode
#10 how deeply they love each other until the very end :'/ sob...sob
