Kevin's attempts to juggle a film shoot, marriage counseling and a charity event go awry when his new "assistants" prove highly unreliable, and Nick's feud with Robin escalates.

Kevin's friends grow increasingly suspicious of his ability to be everywhere at once, especially when Rogue Kevin causes havoc on set and Sensitive Kevin gets a little too close to Akira.

J.B. goes to extremes to figure out what Kevin's up to, Tiffany Haddish helps Robin and Nick resolve their dispute, and Akira makes a big decision when she discovers her husband's secret.

The guys come up with a plan to get rid of Rogue Kevin for good, Trina can't decide what to do about Roland, and Nelly and Angela's wedding day takes an unexpected turn.

After a showdown with his nemesis, it's finally time for Kevin to become the first star among the stars -- but Neil deGrasse Tyson explains that space is actually a pretty scary place.
