The special abilities of the Locksmith, Cleaner, and Pickpocket are fairly straightforward and easy to use. Locksmith simply gains faster picking speed and the Cleaner just knocks out any unsuspecting enemy he runs into. The special abilities of the Gentleman and the Redhead seem a bit more mysterious.
How do I disguise as a Gentleman and when his disguise drops, how does he re-disguise? As for the Redhead, how do I "charm" the enemies and what does this do exactly?
