FBI: International Casts Teri Polo in Mystery Role — Could She Be [POSSIBLE SPOILER]?!

Teri Polo has booked a mystery role over on CBS’ FBI: International — though we have a fun theory on who she could be playing.

Polo of course has starred on TV’s The Fosters and its offshoot Good Trouble, as well as Fox’s one-and-done The Big Leap. And as far as broadcast-TV procedurals go, she had a mini arc on CBS’ own NCIS that spanned the Season 19 finale and Season 20 premiere, playing Special Agent Alden Parker’s ex-wife, Vivan.

According to our sister site Deadline, details on Polo’s FBI: International character are being “kept under wraps,” but this much is known: She will appear in the final two episodes of this season, then continue on into Season 4 if the FBI spinoff gets renewed.

What sort of character would need to be kept “under wraps,” to have any sort of surprise element on FBI: International?

What if it’s… someone we have met before.

Someone very close to one of the agents.

Someone who is… a mother… to the team leader?

What if — we purely speculate — Polo is playing Angela Cassidy aka Scott Forrester’s mom, who was last season at the end of Season 1 wearing Lost alum Elizabeth Mitchell’s face?

Hear us out….

Introduced midway through FBI: International‘s freshman run, Scott’s long-lost mother was revealed to be a U.S. government asset who allegedly was selling information to the Russians. Eventually, the truth came out that Angela was working as a double agent, and that real allegiance was in fact to the United States.

In that season’s finale, Angela sadly bid her son adieu once again, asserting that she needed to disappear anew in order to keep them both safe, seeing as at least one assassin was hot on her tail.

What if in the time since, Angela got a touch of plastic surgery to change her appearance enough to resurface and not be found out — now looking more like Gaylord Focker’s wife and less like Gia Carangi’s girlfriend?

Am I onto something? Weigh in!
