Mozzie

Mozzie is Neal Caffrey's oldest friend and partner in crime, a career con man who trusts almost no one and refuses to give his real name to anyone, ever. Paranoid about the government, allergic to authority, and fiercely loyal underneath the theatrics, he operates from the shadows of Neal's new, uneasily legal life.

Willie Garson plays him as pure delighted mischief wrapped around real tenderness, delivering conspiracy theories and wine snobbery with the same deadpan conviction. The writing never lets his paranoia become a gimmick; it's inseparable from his devotion to Neal, and Garson finds the loneliness underneath the disguises without ever losing the fun.
