I may not be completely into Veronica/Logan (so gag-inducingly called "LoVe") but I am very, very into Logan. If he turns out to be guilty of anything major (murder, rape) I will cry 1000 tears every single day for the rest of my life! OK, that might be a little melodramatic, but I can't help it! I love Logan. I'm so scared that I have actually entertained the thought of being spoiled for the end. But, no, I am remaining strong.
I love it when I let TV have an effect on me. Angel turning into Angelus in "Innocence" would have had no effect on me if I had been spoiled for it. But, I have to tell you that I was spoiled for the Joan/Adam breakup episode. And, that was OK for some reason. Something that shocking I had to have a cushion for. But, I love Veronica Mars more than Joan this season) and I want to watch it no cushions needed.
As for who killed Lily -- I like the theory that
Not Logan! No! No no no!
