I never noticed until this rewarch of VM that in the tenth episode, when Logan's on the phone with Connor's team so he can get Veronica in, he says that her name is Veronica with a V for virgin. Not only is that a throwback to the homecoming episode, which could very well just be that, and a nod to the fact that they were friends (like the line prior to that), but it also indicates, at least to me, that he was provoking her, but not provoking her with the outlandish, often explicit rumors about her (which he only does in front of a crowd, like later in the same episode when he says "ho ho... hoe" in front of his friends). Instead, he provoked her about something he knew to likely still be true: She is still a virgin. Which means that Logan was never really fooled by the whole story on Veronica. Sure, he started it, but we also saw from Pam on the Purity Test episode that he wasn't the only one who went out of his way to invent stuff, and likely the rumors became so outlandish and outspread that he couldn't create all, OR tell which was which---except he could. Cause he knew her. Other people might have been fooled, so called friends from before, friends who came to birthday parties and talked to her, but he knew her enough to know she'd never go to bed with someone outside of a relationship, no matter the 14 score on the purity test, pleasuring the entire swim team, giving handies for weed and a ride home. Cause he knew Veronica before. He didn't bat an eye at her private detective thing, he was frequently the one who didn't bend down because he was aware that Veronica was still Veronica deep down, when everyone else forgot, even Duncan. Which also explains why in later seasons he is so fiercely protective of her, when everyone else except for her dad would think that's insane and she doesn't need it.
I don't know it just hits me sometimes that Logan might be the only person who ever saw Veronica as Veronica. Wallace adores her, but his first interaction with her was when she cut him down from a pole in front of a crowd. Impossible not to make that person into a God of sorts. On her first introduction, Mac pretends not to know her, but then says that Veronica was all people used to gossip about, and though she got close to being someone who saw it, she still truly only met the second version of her. Duncan definitely liked Veronica no matter what, but he was too passive and repressed to give true thought to it. She was his childhood girlfriend so she could be his 'new' girlfriend, sure. Makes sense. The only other person who truly understood Veronica was Lilly. In the homecoming episode, she says she should stop wearing those dresses, cause they weren't her. In her ghost form, she said they'd have so much fun right now, cause she was a rocker chick. She was the only other person who unconditionally loved and saw Veronica as Veronica, without parental hang ups, and she would likely be the only one brave enough to go up all of those people. But she's dead now. Which still leaves us with Logan.
And in the very first episode, when Weevil and the PCH are smashing up Logan's friend's car, Veronica tells them to let him go, she doesn't want his apology. Because she knows that it's grief. Because she is new Veronica because of grief, which is the same reason why Logan is new Logan.
Whoever wrote that our childhood friends are the first loves of our life was so right, man.
