Other mistake: Rob's watch is completely blank. No numbers, no hands or the knob to adjust time. His watch is fake. (It may be that way in all the episodes but this is the first time I noticed it so far).
Continuity mistake: When we first see Richie at the beginning of the episode he has extremely dark "bruises" all over his hands, arms and face. But by the end of this episode all the bruises are gone except for 1 which is on his face below his left eye (on our right). Bruises do not just vanish in 2 or 3 days if they are that bad.
