When the warlock Gavin came back from the future to kill Tanya, Phoebe got a premonition of her death and tried to find her with all the resources she had. Eventually, she found Tanya at Buckland's just in time to prevent her premonition from coming true. While under the Charmed Ones' protection, Phoebe got another premonition of Tanya cradling a baby, and so discovered that she was pregnant, which eventually lead her into figuring out that Gavin was a warlock from the future, who was after Tanya's baby. After Gavin's vanquish, Tanya was safe and sound again. But because the sisters were under the influence of a truth spell, Tanya's memory of this experience was erased after it ended.
