The kitchen is unnaturally bright, with a large pot boiling on a stove behind you, a few knives on a bloodied cutting board, and an assortment of closed cupboards. You try opening a small dumbwaiter hatch with no luck, and turn around to face the new door.
You can:
see what's in the pot,
examine the knives and take one or all of them, even though you already have a penknife,
look in the cupboards,
try operating the stove.
You could also ignore what's in this room and open the door opposite the stove.
