Scarlet Empress thank you for your very helpful comments I will edit the chapter for the POV's.
First off just to let everyone know although Serenity did wake up next to Dracula un clothed he did not sleep with her. He does mention this is one part in the story saying he should have defiled her when he had the chance therefore making Van Helsing the first to sleep with her. So really she has actually been with Van Helsing twice.
When Van Helsing tells her to show where Dracula touched her to replace the memories. At this point Serenity stil believes that she slept with Dracula.
The next morning when they are caught by Carl is when Van Helsing tells him they have not clothes on therefore acknowledges they did sleep together.
I will go back and re edit the 2nd flash back to include the POV's of both Van Helsing and Serenity. The reason there are two POV's is because this is Van Helsing telling what he remembers to Serenity and she starts to remember. Once she remembers that is when her POV takes over.
Reminder the flashback ended because as he said that was all he could remember. Just a note Van Helsing does not have all of his memories either as stated in the movie.
There will be another chapter in which the memory with Serenity remembering her time with Dracula. Probably the chapter coming up next.
The reason Serenity trusts Van Helsing more is because she feels a true connection with him. After all he was the one that made a deal to make her Immortal.
The repeat in the back flash is actually on purpose. This is when their past selves come through somewhat. This allows them to feel more comfortable with one another.
If I have confused anyone I am truly sorry, please tell me your questions in the review and I will do my best to answer them.
There will be at least two more twists in the story and I hope that all of you continue to read to find out what they are.
Once again Thank you so much! Especially Scarlet Empress.
