If your wondering how long Jane Doe will hold on to her Blindspot secret, we can tell you the tattooed enigma will keep her lips sealed through at least episode 13.

'Blindspot' Midseason Premiere Title Revealed! Can Jane Trust Oscar?

Jane (Jaimie Alexander) now knows that she is a riddle of her own creation, but she isn't about to let the FBI in on the secret. Well, at least not until she knows a bit more. Unfortunately for our heroine, a mole within the Bureau will place Mayfair's (Marianne Jean-Baptiste) entire team under the microscope in "Erase Weary Youth."

"After a tip reveals there's a mole within the FBI's New York Office, the team must hunt for the operative while facing extreme scrutiny from Inspector Fischer (guest star John Hodgman)," NBC teased. "The team's deepest secrets threaten to be exposed, and everyone is a potential suspect - but some, especially Jane have more to hide."

The arrival of Oscar and his shocking video threw Jane's whole world into a tailspin in "Evil Handmade Instrument." As the spring run begins, Alexander's character will have to reevaluate her position with everyone she knows.

"The midseason revelation really leaves Jane reeling, trying to make sense of the past, her present and what this means for her future," executive producer Martin Gero told TV Line. "It reshapes her relationship with almost every character on the show... so, you know, it's kind of a big deal."

It remains to be seen when she will finish assessing the situation.

Blindspot will return to NBC on Feb. 29 at 10 p.m. ET. "Erase Weary Youth" will air on March 14.
