Kell quickly realizes that any attempt at magic just gives him more of that nauseating headache. It doesn't mean he stops trying. He's not someone to sit and wait for rescue. If anything, he's the opposite, barely getting enough sleep. Who can sleep when you're plagued by nightmares, and there are monsters, and
the snaring vines, and the ground shakes, and nowhere need of food and water for everyone. Is he needlessly agitated? Yes.

He can be found looking through the blacked corn for some edible ones, picking up weird looking yellow mushrooms.

"Those are edible" he explains to anyone asking, or even just looking at him with interest. "But don't touch these" he points to brown mushrooms with thin, blade-like fins on the underside. "They are poisonous."

He finds plants that are edible, and others that can help in preventing infections, and others that help for stomach problems. His knowledge
of the alchemical ingredients finally being useful for something more substantial than entertainment of ladies that frequent the teashop he works in.

Even weakened and injured, Kell seems to run on pure spite for the most of the week. It's at the end he starts showing signs of slowing down. The hardships of their situation, the lack of sleep, food, water, taking its toll on him finally. He would still try to help, as much as he can, foraging for food, getting water, freeing people from the vines. But as often, he'd be the one needing help.
Especially during the night, when the monsters come out. Without weapons, without his magic, he doesn't know what to do.
