As die-hard fans may recall, Sela replaced actor Connie Nielsen after the FBI pilot, although the reason behind the switch was never fully revealed, per Screenrant.

Connie moved on to many other roles in Hollywood, but becoming a staple in the FBI universe was apparently not meant to be.

Meanwhile, Sela stepped in and played Special Agent in Charge Dana Mosier for the remaining episodes of Season 1.

But almost as soon as she became adored by fans, in 2019, the Season 1 finale would mark the end of Sela's time on the wildly popular CBS show, with her character announcing her resignation.

"So grateful for my time on FBI,” the star wrote on social media at the time. “Such a wonderful show with an amazing cast and crew.”

If she loved the experience so much, why did she leave?

Well, as for why Sela's time on the drama was so short-lived, she reportedly only joined FBI under a one-year contract, which was not renewed, and thus, she said goodbye to Dana Mosier and the series, for good.
