Gus and Martha
Gus hoped that his nerves didn't show as they got settled into their car to go through the haunted house. "Don't push it down too hard," he said to the attendant, wanting to make sure the bar wouldn't cut off their circulation.
"I haven't run into him yet," he said, again, hoping that by focusing on his conversation with Martha he wouldn't make a fool of himself on the ride. "I'll have to tell Shawn that he's here."
Of course, if anyone could figure out that Shawn was faking his psychic ability, it was Sherlock Holmes.
