Fic eating brain, please send help!

Me: Hey, brain, are you sure this is what you want to be writing?
My Brain: Yeah.
Me: Seriously, this epic Merlin fic?
My Brain: Yep.
Me: Even though we haven't written anything in this fandom before? This is what you want to start with?
My Brain: Yes.
Me: Even though it's probably going to be as long as Somnus, which nearly broke the both of us?
My Brain: Uh-huh.
Me: And it's full of OCs and people probably won't even want to read it if it gets done?
My Brain: You got it.
Me: Could you at least decide what season you want to set it in so I know how to write Morgana?
My Brain: Meh.
Me: Well, how about giving me a half decent Merlin voice to narrate?
My Brain: Mwahahaha!...no.
Me: *sigh*
