Jessie

Jessie accepts a job as a nanny and moves in with the Ross family.

Jessie defends Mr. Kipling; Zuri brings home an imaginary friend; Luke and Emma compete.

Ravi is fed up with Luke and Zuri's pranks, so he explains to them about karma, and how their bad behavior will rebound on them. When bad things start happening to Luke he thinks it's karma, until Ravi admits to Jessie he is responsible.

Luke needs a new member of his paintball team on short notice. He enlists a terrified Ravi, but when Luke's team is losing badly, it's up to Jessie to save the day.

Jessie practices her guitar skills and plays in Central Park. People notice her and give her money. While she plays, Luke hip hops and they find out that they can earn more money that way.

While reading a book on psychology, Jessie finds out that having imaginary friends can hinder a child's ability to make real friends. She decides to help wean Zuri off her madeup friends.
