Pre-series – Appendicitis Sam / Big Brother Dean / Daddy Winchester / Awesome Bobby – Dean mentally sorted symptoms and associated diagnoses so he would be ready to triage and treat his little brother should Sam's sickness take a turn for the worst.

We all know Dean takes care of Sammy when he's sick. But who takes care of Dean when he's down and John's away? Weechester!

Pre-Series, Teenchesters – It was just routine surgery. But this was Sam. Nothing was routine. - Sick!Hurt!Hospitalized!Sam, Worried!Awesome!BigBrother!Dean – John, Bobby, and Pastor Jim also included

Brother-fluffy pink kitten/bunny story...Dean age 15. Sam 11 Just a normal little brotherly moment in the boy's young lives. Well, as close to normal as they could get, anyway. Sick Sam. Protective Dean. Some humor.

Dad, that's the way it works. Sam sounded like he was talking to a child...well, someone younger than him anyway. We watch each other's backs. PreSeries.
