The second thing Emily notices is that what's on the other side of the door is not Hank's lab.
"That's weird," she muses, stepping inside and looking around. Surely someone would have mentioned if they were remodeling? Surely she would have noticed it happening?
...Surely they wouldn't have installed a bar?
For lack of a better idea of what to do, she wanders up to the bar, still looking around to see if an explanation for this oddness will be readily apparent.
"This is strange," she murmurs, drumming her fingers on the bar.
Of course. Something green and fruity appears on a (blank) napkin; a new napkin says Milliways is an interdimensional bar which appears beyond assorted doors according to a schedule as mysterious to me as it is to my patrons. I am called Bar, female pronouns please, and while the first drink is free subsequent purchases, which may include not only food and drink but also any other non-weapon non-living non-enormous non-magical items you might care to buy. You may run up a tab. There are inn rooms upstairs, restrooms beyond me and to your right, and a door to the backyard beyond me and to your left.
"...Oh, sweet. So what is this?" she asks, gesturing to the green thing.
"I don't know what that means," Emily admits, taking a sip of the drink. "Aside from delicious, apparently."
A little girl in a red dress who looks like she might be eight or nine steps in.
"...Oh, hi! This is apparently a transdimensional bar, I was expecting somewhere else too."
"I was expecting a laboratory. This place apparently hijacks random doors."
"...I don't think so. It had better not be, that would mean the lab was gone too, and there was someone in there. Bar, the chapel isn't gone, is it?"
"No," shrieks the little girl, flinging herself bodily away from Emily and landing with a nasty-sounding thump on the floor. "No you have to stay back from me."
The girl sits up and hugs her knees. "It's just bumps. I get lots of bumps."
"I--um--are you okay in general, that is not a normal response to. Things."
"...I don't think there are actually rudeness rules about it because there's only one of me."
"I mean there's only one person people have to be away from. And it's me."
"Why would people have to be away from you, though? ...I'm sorry, I'm being pushy, aren't I."
