Maybe he had a few licks of the juicepop during the study session? Also I know all too well that blue-tongue state, after drinking something with Blue Curacao in it.
Actually the question she asks him is pretty dumb. What is a major indicator for Hypokalemia? Hypokalemia means low amounts of K+ (potassium ions) in the blood. So he basically answers her question by saying, a major indicator for low amounts of potassium is a low potassium level...who would have thought...
Lol, I love how there was actually no indication that Carla's sad or mad, you're just projecting your own assumptions about how you think women should react. All men are the same indeed.
You know, the way he said "Why didn't you put another one on?" I'm a guy, but that sounded like an insult to me. But I guess some girls like the childish mindset of some guys
