A... What? Something in Lily's face works oddly for a moment, but it's open confusion. Her brow furrows and she goes through mental rolodexes trying to figure out what the hell he's asking for but she comes up blank.

"I'm sorry, what?" It's clearly difficult for her to even admit defeat, though her next comment clarifies: "I'm afraid whoever told you about that was lying to you, because nothing of that description exists. Phoenix tears are notoriously unstable and can't be saved to be used long-term in potions. I don't know who told you that they could be, but they're no friend of yours."

She smiles tiredly, resting her cheek on her knuckles. "If you tell me what you need though, I can come up with something. I promise I've got some very powerful potions here already."
