[Hange saw the wince, but won't mention it if Levi doesn't. It may be encroaching upon his personal space, but this is on behalf of the greater good and he is in a much better position to play host so he's just going to have to try and make do. Technically it is Eren's apartment too, but he isn't going to get a say in it either. Sorry!]

Then it's settled. I'm sending it out now to the whole group, including Gabi and Reiner. I'm telling them to come over in an hour. The first potions should be ready for use by then.
