Sovie is the one to answer.

"Hello. I take it you're my new patients?"

Sovie looks down at him. "Uh, I don't remember being referred as patient."

Okay, just hearing the word "patient" causes the air around Ezra to chill considerably.

"Until you've been confirmed uninfected, you're my patients, or you're a threat to the survival of our species."

His cane taps against the door as he steps inside.

"That sounds reasonable. What is the problem with your eyes?"

"Temple!"

"Sorry, mom, I just wanted to know if we could fix it."

"If I remember correctly, they were gouged out by a rather frustrating man." 

...

"What does being your patient means exactly?"

"Either you convince me you don't need treatment, or you accept treatment."

"Convince you? I was under the impression the fungus was something testable."

"It's a bit difficult to examine a memetic hazard, but yes, we can test for it in certain cases." 

"I was also under the impression that it was..." shudder. "obvious when the person is infected."

"Usually, yes. I'm inclined to wonder how suddenly appearing individuals have managed not to get infected- or to delay the usual symptoms."

"Is this because you don't believe that we have magic and could've actually come from another universe?"

"That's a good summary, well done."

"Thank you? Is your suspicion that magic isn't real is such that you wouldn't accept if we tried to prove you wrong?"

"You can try. I don't really expect strong evidence, but I'm willing to accept it if you have any to offer."

"Assuming that you are skeptical of second witness accounts. We could give you the memories of someone in the scene."

Temple waves at Ezra.

Ezra tentatively reaches out for the doctor. "Do you mind if I touch you and transfer a memory?"

"Mentioning your ability to affect minds was probably not very tactically sound, so I suppose that lends some credence to your claims. I do have to say I mind."

"It's entirely reasonable to be afraid of people messing with your head. How much do you trust other people's accounts on magic? Because without magical effects and given the... uh, constraints of your lack of sight, it's hard to give you strong evidence unless you have time to prepare. Like, I can absorb heat in my vicinity, but without the visuals it isn't as impressive."

"We can heal your eyes but that would require touching too and I don't know if we- never mind, we can definitely heal one of your eyes and that should be enough evidence."
