July 13th excerpt:

“My back’s hurting, but that’s the same as always,” Sam dismissed. “My legs are what really hurts– we ran all day!”

“I can imagine,” John winced at the memory of jogging for exercise when he was younger and how sore that used to make him. After running for their lives, soreness was the least of these kids’ worries. “That should go away just fine with some stretching and drinking plenty of water.”

One thing did stand out to John and made his brow pinch in concern. “How long has your back been hurting you?” he asked gently, worried Sam might have some sort of condition or injury.

No worries, the faq is not the most friendly for mobile! (There’s a mobile-friendly version here, but this isn’t in the faq anyway)

Dean would definitely be harsher, but he wouldn’t kill Sam right away (one of the times it’s really, really good Sam was found by Dean and not by certain other hunters).

He would likely close his hand around Sam much tighter, though, and confiscate the knife from him before anything else. If Dean takes the time to look at the knife, there would be a lot more shock and demands of where did you get this and Sam completely confused and winded by it all, likely ending up under a vase until they both realize why they have matching knives, and then guilt for the ages for Dean.

December 5th excerpt:

Dazed and bruised, Sam was operating wholly on instinct as he heard someone entering the flat. “You son of a bitch,” he slurred, weakly trying to push his arm from where it was braced to pin him down.

Instincts guided his other hand, and Sam’s fingers wrapped around a familiar hilt. One he’d always kept at his side, but never wielded against another person.

In a flash, Sam’s silver knife was at the man’s throat, trying to force a stalemate.
