[Like so,] says Shell Bell. And she turns invisible and teleports to wherever Tony Stark might be on this world.
That's a weird thing in his chest. She wonders what it is.
Also, he doesn't seem really prepared to receive visitors. She hops to just outside the house, and attempts to add the local Jarvis to the brainphone; this'll simply fail if there isn't one, but she thinks her world is the odd one out there.
[Yep, could you see me anyway? I do that when I'm teleporting somewhere unfamiliar. I apologize for appearing in Tony's room, but I didn't know where he was and the way the teleportation works is I specify a unique location, like 'near Tony'. I have one of him on my world and I heard that this world had one too so I have come to be sociable, but since he doesn't seem ready to receive visitors right now I thought I'd go through you, figuring there was probably a you too.]
[I don't know. Do you know how to open a door to Milliways at will, like the other Jarvis? Because if you don't, I have as long as my friend is willing to hold the door for me.]
[Then my time here is limited unless I want to let my friend close her door and wait until I find a door myself, which has been known to take up to a year and a half.]
Shell Bell visibles and teleports at the same time into the living room.
"Mine, you mean? I call it Atlantis, and it has a one of you in it, only he's my age and he has a twin sister. It's in the future relative to here, and it was until recently a pretty nasty totalitarian state where it wasn't just post-apocalyptic, but I have since acquired magic and fixed the place up a bit."
"Oh, did I leave that there? This is only an illusion crown, I left my real one at home." She waves her hand through it by way of illustration. "Yeah, I go around wearing a crown, calling myself Empress of Atlantis, putting bad guys on the moon. There's lots of me, in various worlds, too, and this is a thing we do is take over worlds and be nice to them."
