"Don't mention it." He really means that because if Klaus went to his other siblings and told them anything about this, Five would either die of embarrassment or kill him.

With his hand now free after his brother takes the glass, Five runs delicate fingers trough Klaus' messy hair. He massages the scalp gently without saying a word, giving as much comfort as he can offer. The teen's body is shaking slightly, he's back to being cold after his little trip to the kitchen, but he doesn't seem to mind being out of bed. He already overstayed and knows that he should leave Klaus to rest in his own bed once the man is feeling better.
