CBS told Io9.com exclusively that Limitless is adding a new character—and it’s played by someone genre TV fans will likely recognize. Here’s what CBS told them:

Georgina Haig is set for a recurring role as Piper. Per the producers, Piper was once like Brian, naive and sheltered—then she lost everything. Now, self-trained in many forms of combat, she has a mission to stop the man who took it from her—with Brian as either her ally or her enemy.

No word yet on when she’ll appear on the show, or for how many episodes. But be on the lookout for Piper, who sounds like she’ll be a loose canon that could kick some serious butt—which could spell either good news for Brian, or very bad news.
