"...oh...that's..." Runo shrank away from the glass a bit more, a little more fearful than before. "W-when you say 'a sample of blood'...how much would that be?" It probably wouldn't be that big a deal; maybe she only wanted a drop or two. It wasn't as if sharks could get in here, right? So there was only really the amount to worry about, right? 

"And...what kinds of other fluids...? You could probably just ask about the rest..." He wasn't sure how much he could trust her with that kind of information, and if it came down to it, he would just let himself be torn apart if it meant the safety of the pod otherwise, but he really wanted to see if there was another way to avoid being cut up or worse. Ideally, he did want to see his companion again.
