She bids her sleeping son goodbye and prepares to head out. Her servant gives her a few weapons before she leaves.

When Sam and Castiel return to the Bunker after the sun was restored to normal, she uses the angel banishing sigil on Castiel and and tells Sam that she is a member of the British Men of Letters. When she asks about Dean, Sam tells her he's dead.

Toni tells Sam that she has come to take him to see the Boss at the London Chapter of the Men of Letters. She accuses him of playing with things,  Archangels, Leviathans, the Darkness, bigger than he can handle. She soon fires a gun at him, leaving Sam's fate uncertain.

Season 12
In Keep Calm and Carry On, Toni brings Sam, who she shot in the leg, to Dr. Marion to have his injuries treated, paying him with $100,000 to not ask questions. Taking him to a farmhouse, Toni explains that the British Men of Letters have kept Britain safe from monsters for forty years and want to do the same with America. To this end, she demands information on all of the hunters in America, their leadership and how to contact them. When Sam refuses to tell her, Toni has Ms. Watt torture him for the information, but he continues to refuse. Though Ms. Watt suggests bringing in Mr. Ketch, Toni refuses as she doesn't like the man and instead decides to resort to mental torture, causing Sam to have hallucinations of dead people in an attempt to break his mind. However, when Dean calls her and threatens Toni if she doesn't turn over Sam, she sends Ms. Watt to kill him. Eventually, Sam apparently commits suicide as a result of his hallucinations, but in actuality tricks Toni and briefly overpowers her. Sam nearly escapes, but Toni manages to lock him in the basement once again.

In Mamma Mia, Toni uses a spell and potion to create a hallucination where she seduces Sam to get information from him. She is unable to get much before Sam sees through it and Toni resumes her physical torture. As she tortures Sam, Toni gets a call from Mick informing her that Ms. Watt is dead and he has come to bring her in as she's gone too far. Toni refuses to stop and captures Dean when he locates the farmhouse with help from Ms. Watt's cell phone and Castiel. Toni threatens to torture Dean instead but before she can begin, a resurrected Mary Winchester threatens her at gunpoint. Toni and Mary engage in a fight that ends with Toni cutting open her hand and mentally strangling Mary while Dean threatens her with Mary's gun. Toni demands the gun, stating Mary will die if she is killed and Dean pretends to comply. As Dean hands over the gun, he punches Toni unconscious, having recognized that she was using a Chinese mind control technique and that knocking her out would end its effects.

The group is then interrupted by Mick who explains that Toni's orders were to make contact with the Winchesters but she went too far out of her belief of their being a malfeasance in the American hunters. Mick promises that Toni will be punished in London for her actions and departs with her. Toni remains steadfast in her desire to get answers, but Mick refuses though he tells her if necessary, he will do what he has to to deal with the situation. To that end, he has called for Mr. Ketch, something that leaves Toni visibly uneasy.
