Mai nodded her assent when she heard Erok's plan, fluidly turning around and stopping for a brief moment, a few strong movements ending in a strong forward push with her whole body, raising a stone wall between them and the waterbending woman, the force of its rise sanding a blast of abrasive sand in her direction, which should at least temporarily slow her down, and she wouldn't be able to bend away a dust-cloud like she could steam. 

Behind the wall, Mai used the small amount of time she hoped she had to strike a wide stance, turning herself and slamming down her heel to raise a set of low stone archways, hoping they would catch the woman unaware when she made it past the wall. Afterwards she sprang forwards once again, hoping to catch up with Erok.
