Tony JR. goes to question the ski lift assistant at the top of the lift the day in question. The kid runs, they catch him, then lock him. When Tony goes to the jail the sheriff tells him they let him go because they have video proof he did not stab the victim. In the video they show Tony as the lift reaches the top it clearly shows the knife sticking out of the victim's chest. But when they showed the lift getting to the top at the beginning of the show the victim's hands are covering his chest until after the assistant pulls him off the seat, that is the first time the knife is exposed to view.
When TJ is scuffling with Macy he throws coffee on her and then for the rest of the scene her face and sweater are immediately dry without a trace of coffee on them.
