Fran (
horrormaster666): Fran and Lilith have a rival-esque relationship. Though she doesn't like him, and he obviously doesn't like her, she finds him bearable over-all. He's bright, and he knows it, and so therefore, he's annoying and arrogant. Knowing that just doesn't make it any better, but she enjoys their banter a good bit.
Hao Asakura (
burnthename): This is probably the most complicated relationship Lilith holds, in that she has both extremely mixed and extremely strong feelings about Hao. First of all, he scares her. He's much more powerful than she will ever be--she knows this--and yet, at the same time, that attracts her to him. This attraction, however, could very easily slide to the realms of lust and such, even if it isn't there yet. They flirt, but that's simply an easy way of making light of their twisted friendship. The only thing she's sure of with him right now, is that she appreciates him a good amount, and is pleased when they get mutual use out of each other.
Karin (
minds_kagura): In contrast to Hao, the relationship Lilith has to Karin is simple. Lilith would kill to get rid of Karin. The older girl interrupted in her attempt to steal Fran's card in the Time: Theory and Practice class and, while she did it, she treated Lilith as if she were a thing that could be ignored and dismissed. In the future, there's extremely little chance of Lilith ever talking to Karin again of her own accord.
Sam Winchester (
demonkiller83): Perhaps the person Lilith feels most passively about, Sam and she are rough on each other, it's true, but if he wasn't so annoyed with her all the time, she couldn't really care less. Might stick her neck out for him once or twice, even, if he did something to prove he deserved it.
Valerie Russell (
swordprince): Lilith sees Val as a potential partner sidekick, and could very well enjoy her presence in the future. As long as Lilith stayed in charge. Which, all in all, is a pretty good feeling.
