I have heard of people undergoing medical bloodletting due to illness and other issues. In my case, it seemed a significant part of the giant's power resided in my blood, so it would be reasonable to spill a bit to improve my condition. It would also nourish others after they ingested it.
"You will suck my blood?" I mouthed to him, not wanting the smartwatch to hear while looking at him.
"It doesn't have to be that way, though I would prefer if there were no trace left after we spilled it." Henry watched my lips, spellbound, before he averted his gaze.
"No, I am asking because I want you to do it." It would be a waste otherwise.
"Good. We'll try that." Henry said, squeezing my hand and fiddling with his collar again. Dr. Lawrence returned with a bottle of clear liquid and two glasses. She sat down across from us, filling the cup.
"This is a vitamin solution. Is touching it enough, or do you have to taste it?"
"Touching is enough." I think.
