The Blacklist will get a visit from Krysten Ritter during season 2, and it sounds like the Don't Trust The B---- In Apartment 23 star will stir up some trouble.

'The Blacklist' Season 2 Will Reveal Tom's Ultimate Fate, Is He Dead Or Alive?

Set to appear in the Sept. 22 premiere, Ritter will take on the role of a "troubled data security firm analyst," according to TV Line.

Based on her past roles, The AV Club was quick to surmise that this seemingly innocuous analyst will bring mayhem crashing down on Liz Keen (Megan Boone) and her team (see video below). While The Blacklist has yet to confirm these suspicious, Boone tweeted Ritter after the first day of filming and told the guest star to hurry back.

"You're such a troublemaker, apparently," Boone tweeted, possibly jokingly. "So hurry, come back and play!"

What fans do know about the premiere, however, is that the script makes Boone illicit an evil laugh to those who haven't had the pleasure of reading it.

"So I've read #TheBlacklist season 2 premier script. Haaaaa haaaa!!!" Boone tweeted on Saturday.

Find out what Boone and Ritter are up to when The Blacklist returns to NBC this fall.
