Later on, Dame is talking to Templar in Blackout. she asks why is he so grim. Templar tells Dame why he served the Dark Covenant for the sake of his daughter Sophia. Templar wanted to Leave the Dark Covenant after he's done with his business, But Dame argues with Templar that Sophia is taken care and belongs to the Dark Covenant. Templar insists that it no longer matters and that he is taking Sophia away, However, Dame mocks him for thinking Sophia would handed over easily and tells him she will be grown up as a operator like them. Templar doesn't believe it, But she tells him that Stansfield and the Fifth Knight filled his head with lies and false promises, Sophia will be an asset to the Dark Covenant and will never let go. Later on, this prompts Templar to slit Dame's throat open with his wristblades, telling her that she has "cut his strings" and that he is nobody's puppet anymore. Dame could only let out a wail of pain until she dies from bleeding out.
However, after apparently killed by Templar, Dame reappears in some time later. During Makarov's Heist at the hacienda, revealed to be alive, and has a job as an arms dealer for an Unknown client.
Some time later, Dame sets a trap for Hidora Kai in The Coast of The Caspian Sea, placing a decoy of Makarov in the event of an assassination attempt. The trap works as Hidora Kai realizes that his target is a decoy, and Dame parachutes down with her henchmen with submachine guns and wingsuits.
