The face Sarge pulls when Addie uses the bad f-word is almost comical, but nothing new. He lost all faith in any possibilities of higher powers around the third month of eating expired cans he found in dumpsters, not all of them meant for human consumption. To this day he holds a certain contempt for people that actually believe that something like a God exists, especially now. All he knows is that if that bastard exists, he is an asshole, and Sarge wouldn't want anything to do with him anyway. So he scoffs at the word, but saves his usual disgust because this is Adelaide and she has always had more sense than most people.
For a moment he doubts his decision to bring the kitten along for her, and this doubt stretches out for the half eternity it takes for her to put her book down and take the little guy. He feels relieved that she seems to like it, and that he can let go of the cat now. "Found him raidin' a hardware store, right where they kept the pet food. Pretty smart, for a cat," he grumbles, unable to keep that last part to himself.
Then he can't really ignore the fact that Charlie is awake, and for a moment some fairly rusty and slow cogwheels are turning in his head while he glares at a point somewhere in the distance, then he gets up and walks into the trailer without a single word, positively stalking because if he does it any slower he might make up his mind, and that just won't do. The little boy is in the middle of a pillow nest, and Sarge finds himself involuntarily going through his dwindling wood supply to see if there is enough for a crib that could possibly be turned into a regular little bed later. Because he knows a thing or two about babies and how they get once they figure out how to roll over, and the pillow barricade won't hold up much longer.
"If you shat yourself I'm gonna have to get your mama, cause the hazmat suits are on the other end of the camp." Not that he is entirely certain that babies understand this kind of thing, but it had never stopped him from talking to small children like they are regular people. The day Sarge starts baby talking is the day someone gave him a full fledged lobotomy. But since there is no stench threatening to burn his hose and eyes he goes and gingerly picks up Charlie, noticing a wet spot and sighing. He has done this more often that he'd care to admit, because Brayden woke up so often in the middle of the night and interrupted what little sleep Sarge could get that he developed what should be referred to as diaper ninja skills. And with Addie being organized the way she is it is not hard at all to find everything he needs to change a wet diaper and find something else for Charlie to wear.
Of course he doesn't comment on that when they make their way back outside just a few minutes after Sarge went in, and he sits back down on the steps with Charlie balanced on his knee as if he has been doing it a hundred times already. Because this is the way Sarge is dealing with things, ignoring them when possible and if not barreling in head first, and this is most definitely the latter option, because this child isn't going anywhere any time soon. "We gotta get this world back in order or this kid won't have any god damn waffle houses to go to."
