Season 1: Episode 4: Nina's Birthday
Fed up with Maya and Nina's constant bickering, Jack asks Maya to throw Nina a birthday party as a goodwill gesture. Maya tries her best to be nice, but Nina's relentless barbs push Maya to her limits. Also, Finch claims that Elliott's success with women is entirely due to his glamorous job, so he comes up with a bet to prove it: Elliott must pick up women, same as always, except he must do it under the pretense of a different job title assigned to him by Finch.
