To be honest, I'd never heard of him either beside the vague notion of him. I wouldn't be surprised that Jack was involved with him. You remember Georgie Porgie? He was thick as thieves with him.
To be honest, I'm hoping so too. With Bigby as my sheriff, I'm hoping to have him there in a bailiff sort of capacity. He'd be able to sniff out things others would. I'd hate to leave you along with them though. Three's a handful for just me. I'm sure that Loki will help out too. I hope.
