3 minutes is a long time to be alone with the corpse of your brother. And for that time, Sam is well and truly alone. He plays through the what-ifs as the seconds tick by. Right now, he is the last living Winchester. He realizes that he includes Castiel in this and the thought catches in his throat.
Seconds to minutes and Sam stares hard. If this is the last time he sees Dean alive, he will remember the hollow ease with which he dug in the needle and the brief moment of relief that flooded his brother’s eyes.
