I felt like I should define exactly what they're even doing from a "science" standpoint.
SO I DID.
The answer is "not much." They don't even have a hypothesis. They just want a general idea if what they're trying are help Nanase think the good, and this is probably good enough for that.
Tedd's not publishing a paper on this any time soon, however.
I feel like I'm cheating by not having Nanase pause for a second before saying "electrodes," which would've implied she had to think about it for a second. It's the sentence the comic ends on, however, and I wanted it to flow smoothly.
If I had to excuse it, she took a moment to think before speaking, so she didn't have to take a moment mid-sentence. She totally had to take a second to think of the right word, I promise you. IT'S OFFICIAL AUTHOR HEADCANON.
