As the Nikita promo for tomorrow night's "Crossbow" states very clearly: Percy must be stopped.

But - SPOILER ALERT! - the mad men will still be at it on the May 18 season finale, as teased in the official CW synopsis for "Homecoming."

Get an idea of how this season, and hopefully not this series (The CW will announce the fate of Nikita on Thursday, May 17), will wrap up by clicking through the following finale images and then reading the network description below...

Nikita and Michael invade Division in an attempt to capture Percy. Alex and Sean get caught in a deadly gunfire battle with the U.S. Marines and Ryan must convince the President of the United States not to destroy Division until he is sure Nikita and Michael are safely out of the building, but the President is eager to end Percy’s reign.

Meanwhile, Birkhoff asks Sonya (guest star Lyndie Greenwood) for help, and Nikita corners Percy in his office, but he pulls out one final trick that may cost her the battle.
