She tapped the powers of Sage and Black Tom and used that to remove the teleflorics. We saw pink energy everywhere when she disintegrated the plant men. I agree with you it’s not the same as the pink firm, but it’s probably the closest we will get.
That’s the closest we’ll likely get to the Bendis era pink powers. The time displaced X-Men didn’t fit into Hickman’s vision and so we will likely see very different evolution for Jean’s powers. I think with the Phoenix being brought back Hickman intends to use it after this Avengers Phoenix story. We will see.
