A/N: My grand plan backfired. So, this is a totally indulgent story. Except it uses the challenge word: 'drip'... so therein lies purpose.

Dean initially jerks away from the ice. Sam catches his ankle and gives him a warning look. "Leave it."

Dean hums, eyes squinty and focused far away. After a minute, he swallows and his eyes flicker to Sam. "I didn't hear a pop. It'll be fine."

"We'll see." Sam is noncommittal.

Trapped in bed, Dean's fatigue ambushes him.

When the ice starts to drip, Sam takes it away. The knee is visibly swollen and starting to bruise.

Dean shifts in his sleep and Sam watches until he settles.

Then he finds the address for the ER, just in case.
