Role in current universe: White Ribbon Drake, a young, straight-laced Bensonhurst rumrunner who's taken the Temperance pledge (i.e.; he doesn't drink.).
Backstory/Description of new identity: Drake's kind of a comic nobody in the gang world. An out-of towner who proved helpeful in dodging the law, he was hired on as a freelancer after several months of hanging around at all the wrong parties looking dapper and awkward. The White Ribbon of his nickname is meant to display that he's taken the Temperance pledge.
Significant changes in personality/mannerisms: a little more focus on being an awkward outsider in this scenario, but not much besides that.
Kinds of CR/RP scenarios you're looking for with this plot: Anything!!
