Honestly I wouldn’t be surprised if he just found that himself while researching. He’s been known to really throw himself into content to read up about roles. When he’s passionate about something, and he usually is, he gives it his all. Dredd is a good example, Almost Human being another. I could easily see Karl pouring over a bunch of random medical stuff. Or even just seeing that he has to stop Kirk in the script and conferring with the on-site medics.

I may be in love with him.
He strikes me as the type of guy who actually listens and asks questions of the on staff subject matter experts they tend to hire on sets.
