At some point, Dullahan began to help S.F giving all the information she knew about Quan Chi and his army. Dullahan had seen this opportunity as a good option to start from scratch and to forget all the mistakes she had committed while under the control of the sorcerer.

Walking among the ruins of her town Deraneus, Dullahan met the thunder god Raiden, he revealed to her the truth of her death and what happened with her town. The real culprit of all was Quan Chi, the sorcerer had ordered his army to end Deraneus. Dullahan was only used by the sorcerer to do his dirty work. Enraged, Dullahan killed the sorcerer, but for killing Quan Chi and without his magic, the strength of Dullahan decreased. But despite that, she had finally avenged her death and that of her town Deraneus. Dullahan disappeared into the shadows of Outworld."

Raiden had a vision in which Scorpion killed Sub-Zero, and the latter would be reborn as Noob Saibot. When Raiden urged Scorpion to just defeat Sub-Zero and not kill him, neither of them knew that Dullahan had heard everything, she went with Quan Chi and told him everything she had heard. The sorcerer had to devise an alternative for Scorpion to kill Sub-Zero. When Scorpion faced Sub-Zero in the Netherrealm and defeated him. Quan Chi already knew what to do after what Dullahan told him and see that Scorpion was not going to kill Sub-Zero. The sorcerer showed him false images of Sub-Zero killing his wife and child, provoking Scorpion's wrath and causing him to kill Sub-Zero.

In the Outworld tournament, in the coliseum, After Sub-Zero (Kuai-Liang, who had taken the alias of his older brother to honor him) will face Reptile and defeat him, Quan Chi sends Dullahan to fight the Lin Kuei ninja, of which Sub-Zero is the winner. And finally he confronts Scorpion and defeats him, but before he can kill him, the Lin Kuei cyborgs capture him and is taken back to the Lin Kuei Temple to be automated.
