Itachi was going to hang whoever showed Kushina how to do that. Still, under the cover of the smoke around Kushina, Itachi had moved his hands through seals already, so a thick wall of earth to protect both himself and Adela was only a flicker of fingers away. Itachi sent his own two water clones darting around the earth, one going for Kushina, and one in theory going in search of one of her clones. In true Uchiha and Itachi style, they were carrying enough exploding tags to blow a small crater in the ground, which should dispel any clones they were near.

Kushina could look out for herself.
