Lily's killer! On TV! Learning to dance!
No, wait, I finally told myself, it's really Harry Hamlin. Aaron Echolls is just the character he plays on "Veronica Mars." But it took a second, because going on "Dancing with the Stars" is exactly the sort of thing Aaron Echolls would have done on the show to save his dying career.
So, in order to keep freaking myself out, I'm just going to pretend that it is Aaron Echolls on the show anytime I see it on.
