Sure, I hope I was of some help..
How? They were arguing, and Logan kissed Veronica.OK, Logan and Veronica started dating, secretly.Until one night, they were making out, and about to enter Logan's house. But walked in on Logan's surprise birthday party, with all of Logan's friends. Duncan walked out, and started freaking out. Which I think brought us to the conclusion, that he has something wrong with him, medically. (he has to take pills). Anyways, so her and Logan went to some room in his house. He left her for a couple of minutes, and Veronica found wires, that led to a camera. She looked behind a cabinet, to reveal, that she was being taped.(Exactly what Lily did, as she was lying on the same bed, before.) SHe thought it was Logan, and ran out. That's why she was avoiding him, and well you know the rest.
What I couldn't believe, was that they just left you hanging. Who was at the front door? I hope they make a season two. That was my all time favorite show.
