Imagining Jade crying, even for something as important to him as an ingredient for a potion such as this, was almost an impossible task. No wonder it wouldn't be an easy ingredient to get, despite being the very type of being that could produce it. "Hm. I suppose that makes sense." And, no, Riddle was not going to offer to help without being asked first.

Not for someone like Jade, someone he was already to wary around.

"That may work. How are you planning to help direct the production of specifically tears? Some form of eyedrop may work, though I don't believe milkweed or any potion of the sort including it would be safe for the eyes.... then there would be the added difficulty of extracting the tears from the drops they'd inevitably mix with. So, then, what sort of mix are you thinking? Potions tend to be indiscriminate unless you manage to use the right additives."
