Hello Leigha! I will do my utmost not to have Dean call your character a Rin Tin Tin and various dog nicknames because that's what I'm always reminded of when I see Tin Tin's name.
pft, I'm sure the urge will pass!
And he does sound really interesting. Marina is lacking in detectives!
And I am Parsnip and I play several characters: Hei/Li from Darker than BLACK, Diva from Blood+, Dean from Supernatural, Fou from D.Grayman and Oz from Pandora Hearts. Don't worry about remembering who I play! The key is just to tag whoever sounds interesting to you and start building up the CR. Everything else you can figure out as you go!
