Oh, dear! Poor Dean!
(Sam would never let him hear the end of it if he had to give up his good boots and ended up walking back to the Impala in socks)
Lucky Sam doesn’t sink into the wet cement like Dean does, so he can show Dean which way to go where the cement is hardening more. And keep out from under Dean, in case his older brother stumbles and flails when he’s trying to pull his boots out from the suction of the cement!
All in all, Dean is very lucky Sam can’t carry his cell phone around, because there would be some very compromising pictures of a normally-suave hunter.
