Is she... trying to measure a property of internal bodily gloop... that has... something to do with hitpoints?
Creation will attest to the part where, at this point, Esta has taken enough damage plus nonlethal damage that he is not gonna just wake up, here. Inflicting an additional HP of nonlethal damage, or whatever it is the entity is trying to do to Esta, is hardly going to help.
His eyes... probably go on functioning... as eyes? Given that he's now apparently almost entirely alive?
If the entity starts wanting to measure eldritch percentages having to do with Esta's internal body gloop then, like, that is between her and whatever Reality Marble this Far Tapestry creature is unwittingly imposing upon her own surroundings.
