For a second Ryan freezes, because the last time he's heard someone yell like that at the 'man' figure, it hadn't gone well.
Trey once yelled at one of his Mom's boyfriends like that when they were younger.
Trey had ended up in the clinic with a broken arm and a concussion.
He freezes because even after almost three years with the Cohen's, a small part of him is still the cocked gun, trigger pull away from being shot like a bullet into the past.
Breathing functions stop and instinct takes over. Don't move, be inconspicuous, keep your eyes level and don't draw attention to yourself.
It was the Little Brother Survival Guide of the Atwood clan.
It's only for a second though, cause then he remembers where he is, whom he's with, what this family- his family, is like.
Remembers that Seth doesn't know the Little Brother Survival Guide because he's never had to learn it.
Then Sandy starts to laugh because as serious as Seth is trying to be he's holding a cob of corn and a person can't really get less intimidating.
Ryan joins in the laugher, relieved and amused. The tension leaves the room as it leaves Ryan's body. The cocked gun is made from cheap plastic and he can finally relax.
A little more sand banks his go-to instinct and he knows next time it'll take that much more to send him back to that place.
