In the season 5 finale, Michael told Fiona that when it comes to her there is no line that he would not cross. However, Fiona decides that she has had enough of Anson and that she cannot let him continue manipulating Michael and decides to turn herself in, and Michael watches in agony as the love of his life goes to jail. With Fiona in jail, this leaves Michael a chance so he can take down Anson, once and for all. Fiona is taken into custody for the deaths of the security guards in the British Consulate. In the first episode of season 6, she is interrogated by Agent Bly. He offers her a deal: give up Michael's involvement in the bombing in order to not face the electric chair.
