I think the complaint about "Belle" is that she should be saying "I'm not 'Belle,' I'm [insert unknown name,] and I want to go back to the psycho ward because I'm hallucinating!"
Yeah, the writers are probably kicking themselves for not giving the forgotten inmate a name before now.
I did like the (literally) running gag about what exactly David/James/Charming's name was. I'm pretty sure my girlfriend and I have had that same conversation?
"What's his actual name again?"
