She is humming, softly, and swaying, slightly, as she scribbles in her notebook, just aimless brainstorming that circles back to the same points oftener than not. Either way, she isn't paying much attention to her surroundings, even as the door closes behind her, and almost bumps into a table that wasn't supposed to be there before she looks up.
"Wow. That would . . . that would be amazing. I have no idea if God would permit it, Hell is supposed to be just and deserved but also God was willing to send His Son to die to save us from it but also if He wanted to destroy it He would have . . ." Bruce trails off with a shrug. "It's a pity you got me instead of someone who understands theology at all."
"In my world, let me try to remember this right, nobody was originally supposed to go to Hell, but Lucifer--um, one of the brightest angels--rebelled and was cast out of Heaven and Hell was created to hold him, and then humans were created with free will and chose to disobey God, and that created sin, which separates us from God and condemns us all to Hell unless we're redeemed by grace." Also he's curious how Hell can be an accident but he doesn't want to sound like he's questioning Christina's omnipotence or anything.
"There are no fallen angels in my world, demons are just something that...happens. Probably spontaneously, but it's possible they're caused by intelligent action somehow. Hell was an unintended side effect of the invention of a self-perpetuating system of immortal souls and there's a lot even I don't know for sure about it."
Bruce runs his hands nervously through his hair. "So. There's a thing I should really clarify. Which is that. My world's God claims to be omnipotent but I have a lot of doubts about it. Because there are things where it seems like He's acting under constraints. So I don't actually know." Bruce gets steadily twitchier over the course of this explanation.
"Mine is aware that other universes exist, but They're not omniscient about them, no."
"Okay. By the way, what, er, is Your relationship to Your universe's God? If that's not a rude question. Just, You talk about Them as if They're a separate person."
"Ah. Yes. That's accurate. Sorry, thousands of years of Christian theology, but at least in my universe, homoiousios was right all along."
Bruce is failing high school theology (a predictable consequence of spending every class trying to think about anything else), but he has enough context to remember which one that is. "Huh. I guess enough other stuff is different that that isn't really evidence of anything on my end. So, um, what happens now?"
"Hmm...I think what happens next is that I invite some angels in from my universe so if I get stranded in yours we don't lose access to this place, and I step into your universe and try to talk to your God."
Meeting angels should not be terrifying after meeting the Messiah; he swallows hard anyway. "Okay."
She gets up and crosses back to the door and opens it and sticks her head out for a few minutes.
When she pulls back in, she's followed shortly by a small and outwardly-unassuming crowd of what is presumably not actually a handful of humans of varied ethnicities.
They certainly look a lot chiller than even the least frightening angels he's seen in pictures, but on the other hand they're not pictures, they're right actually there. Bruce gets up, aware that he's making either the best or the worst decision of his life (or was that when he entered the bar?) and opens the door.
She strides forth.
Hello, she prays, and sings in the inaudible tongue of the angels, I would like to speak with you.
She gets a response; not in a language, in direct concepts-only telepathy.
WHAT ARE YOU
She does not resort to words either, offering up her identity and the nature of her world and her God and Milliways and how she met someone from this world and was exceedingly curious.
This gets a noticeable pause.
But does she acknowledge him as the LORD of all that is, that's really the important question here.
Well, like, probably, but she wants to make sure she's fully informed about the situation before committing.
