The second-floor janitor's closet. Harpuia filed that knowledge away for nightfall; while a pipe was by no means considered a sophisticated piece of weaponry, it'd be sturdy enough to serve the intended purpose. He'd rest much easier knowing he could defend himself properly, though he did stop to wonder exactly how he would go about concealing something that size from the nurses. A matter to consider later, perhaps; it obviously could be done, or there would have been no point to making the recommendation in the first place.

"Thank you. You've been extremely helpful. I'm sorry that I can't offer you anything useful in return, but I don't intend to forget the kindness you showed me." It was a bit... serious, as far as replies went, but that was just Harpuia's nature: he took things absolutely seriously.
