"Sure, if they have business on one of the other planets and a teleport with the range or access to a portal  - or a couple of plane shifts, though that sounds like an awfully bad idea if you ask me."

"Why's that?"

"It's not very accurate about targeting on your destination plane, and lots of planets aren't very safe."

"Around here they mostly don't have air."

"Lots of them don't! Or too hot, or too cold, or made of gas, but there's spells for all that. Landing really far off your destination could be really dangerous even if you're prepared for all that."

"Huh."

"Where are we going now?"

"Karen's. So you can do that scry."

"Is there anything we should know, meeting her family?"

"She lives with her sister and her sister's kid. Her parents are dead."

Sister's kid's father - he shouldn't ask. 

"My condolences."

"Just mind your own business and don't be a dick."

....is he warning them not to pick her up? Where've they given the impression - "of course."

He drives the rest of the way in silence.

Her sister answers the door.

"Hi Alex. Hi weird interdimensional visitor people. They speak English?"

"I do, temporarily," he says. "They don't but they can understand it. Nice to meet you."

"Cool. Azalea Teller, nice to meet you too."

She offers her hand for a handshake.

They look confused and do not touch her.

She looks amused. "Is their dimension devoid of handshakes?"

"I'm afraid so. People touch each other to introduce yourself?"

"Maybe one shade friendlier than waving hello. I guess I don't know if you people wave, either."

He waves, a little awkwardly. "It's nice to meet you."

She stands aside and holds the door for them without specifically waving them in.

Sensible thing to do if there are vampires about. Not being vampires, they enter.

Karen descends the stairs.

"Oh! Hi. Let's see - I'm me, Azalea's my sister, Connor's my nephew in the next room, and that's Wishbone. He's a person and a magic expert, be polite."
