Delilah's Links
She thought that Blood was too naïve and "good hearted" to notice her using her to get to her older brother. She tends to spoil her with gifts, joining her (and sometimes with her brother) for a meal once and awhile, and "willing" to help her with her magic lessons. Unfortunately, unbeknownst to Delilah, She didn't fooled her. It was only Blood's good nature that she didn't call her out on it. It took her teaching Blood (and many meals without Pulse there to distracted her) for her to get to know Blood built a genuine friendship with her. (Too bad that this stunt has her on Pulse's hit list)
Blood and Delilah's relationship started out rocky with her trying to use Blood's innocents and kindness. Unfortunately for her, Blood saw through her from the start (not the very start but within maybe a week or so). However, being the kind vampire she is, Blood was willing to give her another shot as she didn't think Delilah was a bad woman. And in the end, the fake friendship did became real. [She doesn't know that Delilah was using her to get to Pulse.]
Her feelings towards him are neutral. Though she does try her hardest to maintain a good relationship with as he is a fellow Noble.
He knows she a Noble, but doesn't really care all that much for her. While yes he does visit her for clan reason, (or being Blood's temporary bodyguard when she need to do something for her brother) he doesn't really have an opinion on her.
The word love doesn't cover what she feels for this man. She obsessed with Pulse that she would do everything to gain his notice.Even using his beloved sister to do it. [She doesn't seem to know that he's using her, or if she does she doesn't care]
He see her as a pawn and he's not above using her feeling for his gain. He also has no problem leading her on (rather using simple, empty, sweet words, some kind of physical action (hand holding, kissing her hand, ect), or sexual favors) He will admit she's beautiful, and hadn't she try to use his sister to get to him he would have continue to be indifferent towards her. (Maybe would have been "nicer" to her in his manipulation)
She's convince that all the looks she gets from him is jealously of her with Pulse. She is aware that Pulse is using him to Blood safe, so she think Vein wanted to be with Pulse. So because of that, she always make sure to flaunt the fact that she has Pulse and not him. Neverminded that fact that she delusional in thinking that Pulse is not using her and Vein is much more "in love" with Blood.
He has no ill feelings towards her, however he has no pity for her as he watch her getting use by Pulse. (He believe she had it coming) He doesn't understand why she think that he in love with Pulse, but he not going correct her as he has better things to deal with. [While he's unsure with feeling for Blood, He rather marry her then her brother]
Delilah is jealous of this woman for being close to her man. She believes that Plasma is also using Blood to get to Pulse (like how she did). So she decides to flirt and use her for information (albeit terribly). She ironically doesn't notice that she is doing the same thing that she fails to notice Pulse is doing to her.
Plasma feels sorry for Delilah as she watches this girl being used and manipulated by Pulse. It doesn't help that she herself has a massive crush on Delilah and is jealous of the man. Though given what she has seen when she is interacting with her, trying to use her for information, she is questioning her taste in women.
