Rosalyn Bain

Rosalyn Bain was the wife of Reginald Bain, mother of Sophie Bain and Audrey Bain, adopted mother of Tovar, and a tactics instructor at Starfleet Academy.

She was also, unbeknownst to her husband, a Section 31 agent.

Rosalyn was sent by Section 31 to protect both the Federation's peace talks with the Breen and her husband's life. With the help of her adopted son, Tovar, who already knew that she worked for Section 31, she was able to stop a holographic assassin. Despite this, Bain decided to leave Breen and let other diplomats handle the peace talks. Before leaving as well, Rosalyn cloaked herself and beat up Thot Phul, who had hired the assassin.

Since she didn't want Bain to even consider going back in time, she used Section 31 technology to go back to the USS Secondprize when Jaroch was captain and got saved a copy of his pattern in a transporter buffer, which she then sent to Bain. He used that to create a body for he Interloper life force to go into when it was transferred out of Tovar. (Mind If I Play Through?, Aren't You Dead? [BG])

While fighting Fubar, a Cardassian terrorist who was attempting to crash a shuttle full of explosives into Paris to kill the Federation President, Rosalyn was able to divert the shuttle's path, crashing it near her home in England so that she'd be back in time to greet Reginald and Tovar. Fubar escaped being killed and got the drop on Rosalyn in her own home, knocking her out and then tying her up. He was delighted by the past lives of Tovar, who cooked and cleaned for him. Fubar planned to take Tovar with him after he killed Rosalyn. Tovar was able to get his past lives to work together to build a device that coated Fubar in a shell of quick-drying chocolate, rendering him immobile. He was then beamed away and imprisoned by Section 31. (The Ties That Bind [BG])

He realizes Section 31 must have captured him again, but he is content to stay there biding his time until another escape opportunity presents itself. And then his holographic crewmates begin beating him relentlessly. Back in the real world in the control room of the Section 31 facility holding Holo-Kirk, Rosalyn Bain tells the Section 31 agents to keep Holo-Kirk imprisoned this time. She exits to the corridor where Audrey is waiting for her. Audrey expresses how difficult it was to pretend to help Holo-Kirk and lie to her father. Rosalyn assures her that she will get used to it. Realizing that things were not going his way, the Kirk hologram tried to transfer his program to an Yridian ship, but he was intercepted by Rosalyn Bain, who took him back to the Section 31 facility. He was returned to a holographic simulation of his USS Enterprise, but one where holograms of his crewmates beat him relentlessly.
