"Oh. Well... well, hmm. In that case I might have to bring Chris to... or, no... I'm not sure. This is complicated. Definitely calling Chris is an early step," he says. "Um, the thing about you being the test case is that this place doesn't show up for just everyone, but once it's shown up for someone once it will keep doing that, but it won't always do it very promptly, and time moves weirdly between worlds. So I would rather ask you to wait by the door while I lean out and call Chris than complicate things by having you go find someone you think would be a better test case and convince them about the magic interdimensional bar and wait until you find a door again while your person is reachable, and then wait for both of you to find me, and then lean out the door and call Chris. It is better to have the person who will be the test case right next to me when I call Chris in case she wants to talk to them specifically. I guess if you have someone in mind that you know you can go get while still holding the door, then you could go get them. But not if they are a baby, I guess, because then you couldn't bring them into the bar?"
He gets up (abandoning his book) and goes to the door and opens it and leans out and says "Kolya can I have the phone please."
Nothing happens.
"For reasons," he adds.
A moment later, he is holding a phone.
"I have a thing I want to use wishes for," he says. "It will probably take a lot. Milliways is involved. I can't imagine you don't know about Milliways, I will be very surprised if you don't know about Milliways."
"I have met someone here who I would describe as most of a dragon," he says, "and I would like her to be the rest of a dragon because being most of a dragon looks terribly uncomfortable and she seems really unhappy about it. She says there are a lot more most-of-dragons and we would like to fix them all. I don't know how big a wish it will take or even if a wish will do it at all, but I really want to try."
"...All right. Will your 'most of a dragon' fit through the door? I'm... going to have to make a few calls, and then I might want her to talk to me. Or to somebody."
"She is currently human-shaped and will fit through the door just fine," he says. "And probably not have very much of a problem using the phone."
"Kolya please hang up the phone," he says. "Chris is going to call me back. Also can I bring a person into our living room?"
"I talked to Chris and she is going to talk to some other shady wish-mongerers and then call me back. Would you like to come into my world to wait to talk to her or whoever she gets on the phone? Does your world have phones, do I need to explain them? And you might be waiting for a long time if I let the door close, because the frequency with which I get doors behaves unpredictably, so I can stand there holding it open if you'd rather. And I have an invisible roommate who will probably be around being invisible."
"A long time could be a week or something. That's the longest I've gone without a door when I wanted one, and wanting one makes a difference."
He goes to the door, opens it, and addresses the empty room.
"Kolya can the person maybe stay with us if she comes in and Milliways has a sulk?"
