John's response to Sam's statement was a noncommittal mutter before he drank from his mug, as the way John saw it, he did have to wait up. The house was too active during the rest of the day, which was also why he suspected Sam was choosing the night to do this. The faint smell of 'bar', one John recognized even now when he was confining most of his own drinking to the early morning, coming off his son told him he had guessed right in suspecting Sam was off drinking this time, rather than off training up the powers John was pretty certain Sam had been stuck with again.
It wasn't exactly a conclusion that pleased him, as while he could try to stomach Sam sneaking off because he wasn't ready to admit he was back to how he'd be pre-pits, he couldn't in good conscience accept that he'd let this go on long enough that drinking was taking the front seat.
"Sit down for a minute," he said, holding out the second mug of coffee. It wasn't an order, not exactly, but John did expect him to do it, and not because he'd ordered it, but because he asked. They might have only been on strained terms since those damned pits has shown up, but it didn't change one crucial fact – a parent didn't stop loving their kid, not even a dad who wasn't so certain he was capable of as much love as he'd once been.
But then again, if he hadn't been capable of it, he wouldn't be here right now. Sometimes the most obvious things were the things it took a person the longest to see.
