[Closes his eyes to that, tearing up and not breathing for a moment, trying to control himself]
Yeah. Guess I'll never know for sure, though. [He doesn't even know anything about her, either. And even if the musketeers are his family and he'd never want to be without him, it still hurts to have the unanswered questions.]

[Breathes out shakily and draws back from the hug, but just so he can cup his face gently, looking at him]
I know that this isn't what you wanted, Aramis. I know, okay? You can look at Snow and David and see everything you wanted and it hurts to see it even when you're glad that they can be happy.
But you'll watch your son grow. [He WILL be alright once they return home.] You'll be able to watch over him, know him, see him and protect him. I know that isn't what you imagined, but it's... that's more than some people get. Even if he only knows you as a loyal servant and musketeer, he can't and won't doubt that you love him. He'll know you. And you'll know him... [he knows that isn't the same as him being able to be your son, but... but at least it's something.]
