Ok, could this episode have been more scooby doo!? The footprints leading into a dead end. If you wanted it to be secret, like it was made to be, why would you leave such ovious footprints? Also my grandma was in a wheelchair for 50 years, and they don't leave tracks unless you are booking it, like a skidmark when a car is stoped and then it goes again really fast.
I love Castle, but come one you can do better then this! This is saturday morning cartoon style, not prime time crime show! Come on Castle, pick up your game!
