Uh-huh. Well, he can have a medical lecture too, though at one point he slips a note to one of the uniformed locals: Tall pretty guy in high fashion, he a human doctor like everybody else or what?

"Matt Carter is the director of the Bureau of Environmental Enforcement."

"Environmental Enforcement? What's that?" Cam whispers back.

"It's the department that handles all the supernatural stuff."

"Mkay. He's interested in medicine or just me?"

"I wouldn't know, sir."

"Uh-huh."

When the snack break is over Cam resumes talking about autoimmune diseases. He's redacted a few textbooks and drops instances of them into the crowd as their contents become salient.

His audience has presumably had a long day but their interest does not diminish in the slightest. They're gonna be able to advance so much science and save so many people.

Yes they ARE!

This is all a high-level overview - he's doing a lot of shortcuts on the level of "here's the chemical structure, here's its mechanism of action and side effects, DIY the synthesis and FDA approval we're moving on" - but it still takes ages. He manages to cut it down to 18 hours of the most important stuff.

Some of them nap. Some of them just share around a lot of Adderall under the mildly disapproving eyes of their military escort. They are so so delighted.

(Matt Carter doesn't nap or do drugs. He makes friends with the reproductive biology specialists at his table).

Cam incidentally takes credit for the in-progress eradication of the malarial mosquito during this lecture.

What. What!

Some people start crying. Some people are Concerned.

"It'll be fine. They're not nearly as ecologically important as you'd think."

This doesn't totally reassure everybody but they move on eventually.

Cam has more exciting revolutionary medical advances!!!!

And eventually he reaches the end of his prepared remarks and can take questions from anybody who is still awake.

The questions drag out the whole event for a lot longer. More people trickle off for naps.

Cam swigs coffee. He does not nap. He does have some - uh, speculation - about ways to encourage best practices in the general population with respect to STIs, yes, how good of you to ask - that's a great question and he's going to answer it with a cryptic remark about the replication crisis! - no, that one's not safe in pregnancy, he recommends this alternative in those cases - anyone else?

Eventually everyone is either out of questions or too tired to ask them.

Cool. Cam turns off his projector.

Grateful, dazed, happy scientists trickle out.

(Carter doesn't.)

"Can I help you?"

"I take it apsels don't need much sleep."

"We can sleep but it's not necessary, not since the invention of coffee." He lifts his mug. "Does whatever you are sleep?"

"We do! But not quite as often as humans, conveniently when time-travellers want to dump a lot of science on us. - convenient under a lot of other circumstances, too, really."

"Sleeping's a bad deal! At least on a daily basis, it's nice every couple months. What are you?"
