Children dealt with plenty of difficult things. Merlin's pants - Remus had been bitten as a young child and as far as James was concerned having James Potter for a father was nowhere near as bad as that. You just had to spell it out in ways kids could understand, incrementally. 'Your father was dead for a little while' didn't seem nearly as daunting as the sort of conversations James'd had with Lily - how the hell do you explain to a toddler that the reason people are out there actively trying to kill him because he's going to defeat the darkest wizard who'd ever lived, saved probably the whole world- and that none of them really had any idea how?
"Well if track records are any indication, I'm incapable of having a child under typical circumstances," he sighed with a small roll of his eyes, letting his body withdraw a bit from hers.
There were the makings of a fight here. But James didn't want a fight. He didn't want her getting upset. Actually, what he wanted was for her to very calmly just... sit down somewhere and try to avoid getting too worked up over anything. And eat something. James was pretty sure she barely found time to eat when she was working and that just wouldn't do. Overlooking yourself was something that happened, they all did it, but it wasn't an option for her anymore and James had no trouble whatsoever being the one enforcing that. Pulling two bowls from a cupboard, James began spooning beef and noodles into each.
"It's not going to stay a secret forever, you know that," he mentioned, meaning the whole zombie thing, and forcing himself to be more accommodating. After all, he wasn't the one being subject to a whole slew of hormonal torments. Pregnancy could make women completely crazy for days at a time and the only thing you could hope to do is ride it out, move slowly, and speaking in calming tones. Turning back and handing her a bowl and a fork, "Eventually people are going to find out. They always do. And then it wont matter much at all. Every family's got something they had to deal with, and we're not going to be dealing with this one by pretending the kid's father doesn't exist."
Though his tone wasn't argumentative, it wasn't something he was going to relent on. They were not going to pretend like James wasn't this child's father, and they weren't going to pretend that he'd up and left Amarissa high and dry. It was possible to try to say that he was someone else, anyone but James Potter, but he wasn't about to even entertain the idea that they conceal the child's relation to Harry. That wouldn't be fair to either of his children. Merlin, what a thought.
