After the attack after London (ww3) Alucard came back from the dead even though he's still dead since he was a vampire , The No Life King. He eventually ended up with Integra though she was against being a Vampire. Seras had a realization that even though she had her master and sir Integra she was alone but captain Bernadotte reminded her that he was inside to always remind her that he was always there. She appreciate his loyalty, she found herself telling him about her past and what an orphanage was like. Bernadotte wasn't fazed because of the fact when Seras drank him up and she became full vampire he protected her memories from Zorin blitz, he saw her memories in the process of helping her.

At nights when the red full moon comes seras still is not use to the feeling of wanting blood and finds herself losing control. Captain Bernadate can't do anything but try to subdue her with thoughts, she eventually calms herself down. but she refuses to drink anyone's blood except her master because the blood she consumes essentially becomes a part of her so she doesn't drink just anyone. Her and her Master had a bond of Vampire but almost in a Romantic way because they were the only two of there kinds. Although they don't say in words, In actions is when you see it. Fighting along side each other, beautiful harmonization but with the captain was more powerful bond, the one she loves is literally inside her. He who kissed her as he was dying made it a special moment for her even though she had to remember him dying, she realized she lost the one she loved and made her finally realize that drinking someones blood, there soul becomes one w/ each other.

So this time when the full moon arose Alucard wasn't there to help her subdue the urge, She also felt her body heat up from the urge of other things. She had the throbbing inside herself, She was an animal in heat (not intended to be sexual, promise). Obviously Captain Beranadotte knew he can hear her thoughts very clearly, she was longing for someone. someone to save her from her nightmares. The memories of tragic and horror repeating it's self in her head, the mortal side of Seras was gone but her consciousness is still intact. The misfortune that befalls a monster is that you want to be released by this curse, Feeling as a child trembling trail of death following you until your existence is no more.

The only sanity is the voice of Captain Bernadotte, His calm, Cool, Raspy voice. Melts your heart w/ each sound coming out of his mouth. His human memories reminding Seras about the good things in life. Although not exactly Alucard but she and Bernadotte were together every waking moment they were together.
