Yea sam was pretty quiet. It's good sam stopped Ryan from doing whatever he was gona do to Travis.
Yeah, it was the right thing for Sam to do (positioning himself so there was a bit of a physical barrier there). I'm pretty sure Ryan was all talk (yip yip yip yip yip... like a chihuahua that thinks it's 6 foot tall and bulletproof).
It probably wouldn't happen, neither inside the house nor out... but honestly, who do you think would take out a fight between Ryan and Travis anyway? (Hint: it's not Ryan)
