"Not yet, I don't know how to set one up on this world's internet."

"Would you like me to walk you through setting one up?  You can do that for free, now."

"Sure. What kind of local device will I need?"

"Any computer that can connect to the internet.  There's one at my desk."

"Are there smaller more portable models?"

"Yes, but if we set up an email for you together using mine, then anything I send to you will be there waiting for you when you log into it on another machine."

"Yeah, I just wanted to make sure that littler ones have been invented. Can you name a small portable one for me?"

"Like a Jade, or an SNSV?"

"Are those specific models?"

"Ah, no."

"Can I trouble you to select a model?"

"Sorry, I don't know any."

"...okay, I'll set up an account on your machine and get my own sometime in the future." Is it hard to get an email? What kinds of domains is he looking at?

The teller is so relieved.  It isn't hard to get one, given that the she has an invitation code she lets him use, but there's only one domain to pick from ('ucom.alf', with the same strange 'on' symbol before it as Andrea's had).  "It was this year's birthday present from the spring equinoxes, you know.  I think it's the best one this octade."

"I'll have to take your word for it." Is the username "cam" taken?

Yes!  The signup page doesn't automatically tell him this; he has to try and submit it (along with a password) before it declines him.

How about "revelation"?

Open!

Cool. He has a new email.

The teller (who made a show of turning her back while he typed in his password) writes down his address next to a note to ask her coworkers about Britannian banks.

"Thanks. The card will work abroad, yes?"

"Anywhere that takes cards at all!" she reconfirms.

"Great. I will wait to hear from you on banks in Britannia. Thanks for all your help."

And out he goes to meet mad scientists.

There's security personnel at the building.  One of them is visibly ellipsising about Cam's approach and the rest are currently ignoring him.

"Good morning! I'm Cam! Here to talk about mad science!"
