To be honest, it really isn't the matter of wanting to RP a certain something, more like rping at all.

I'd really just like to sit down and make a plot, characters, premade if desired. Kind of go off of something we both like and work from there so that way it really isn't just one sided and both parties can both rp with peak interest.

The serial killer one was a fun one because it is something different. The plot I used and created for that one was slightly basic, he was placed in an insane asylum which had lost its funding to fully support all the clients which were placed there. So with miniumal guards he was able to escape. With the character having multiple personalities, each of which have a specific profile they are after. The way we made it was that he met a woman who didn't have any of the characteristics that his personalities wanted. So he felt safe with her.
