Well, Skippy!Rat did amuse me so. The hair, the suit, the puppyish dogging of Mulder, the infamous red speedo scene (and he was so checking him out). And the look that he gives Mulder when he lets him have the keys is just heartbreaking.
Hooray for M/K slash in canon.
Also, I find that the more episodes I watch, the more endearing Mulder becomes.
*is now eagerly awaiting season 3 from Netflix* (though I really want to jump ahead to Tunguska)
