It's a Whole Different Thing All Together

It hit me while re-watching 'Shawn Takes a Shot in the Dark' that Shawn had no way of knowing for certain if anyone knew he was in trouble. Until Henry and Lassiter show up at the gas station, he couldn't be sure that anyone was looking for him. And just to be clear, this is not a missing scene. This story takes place at least a few months later - maybe longer - it's up to you.
