Five can't possibly be much colder than Klaus, that with his own elevated temperature, but it's more clear to him now the other man's shivers are due to some sort of night terrors.

"Stay. I'm rested enough for a jump or two now. The pills helped." .

Father pushed him this much when he was little and had just discovered his power. The man wanted to know how many jumps Five could make in a row, what distance he could cover, if freezing or scalding temperatures affected the jumps...Funny days, those. He couldn't even walk after the experiments, now it wasn't so bad.

He waits a few more seconds before retreating his hand, a blue glow surrounding him before Five is gone. If there's the sound of a chair falling coming from the kitchen, well...little accident happens.

When the boy comes back, he's holding a tray with a big jug of water, so they don't have to repeat this later if they get thirsty, and a small, two clean glasses full of water and a damp towel. He leaves the tray on the bedside table pretty quickly, it's heavy and it doesn't look like Five is really able to handle its weight for much longer.

"There..." One of the glasses is offered to Klaus and with his left hand, Five grabs the towel and presses it against his brother's nape.
