Sherwood sees Noctis leave the boundary he'd created before, the Grimm still contained in the area. Acting quickly, on reflex, he uses his semblance. He launches from his draw hand a streak of lighting, which hits the grounded arrow nearest to him. The lightning then flies from the first arrow to the next, and the next, extending into a fence of electricity. As the lightning hit the final post of the fence, Sherwood wills it to cycle to the first arrow again, creating a closed loop. Letting the electricity do what it does, Sherwood returns his attention to the beast he's now encircled with Ar...gent.
Sherwood frowns seeing that Argent was not in the area with the Grimm, but Persimmon who had burst from the trees. Persimmon isn't a melee fighter, as far as Sherwood could tell, and being in a bounded field with a massive Grimm isn't going to be good for him. "Argent! Persimmon is going to need your help in there!" he shouts.
Sherwood pulls his bow back, and starts ratcheting up the weight on the bow. His focus not on his form, but on the status of his partner in the arena with the Grimm. Sherwood watches, waiting until his partner is about to be injured, covering the fox faunus of at least one attack with as powerful a blow as he can must in the time frame.
