Helen is shown as not being able to behave when she is in the set of "FBI's Most Wanted". However, in "Helen's Surgery" Drake and Josh visit Helen's apartment and are impressed about how rich Helen is. She then confesses it is because she was a child actress, which means she should be able to act and would be fine when in a set.
Josh being mistakenly assaulted by bystanders and arrested by the police was complete unnecessary. On "FBI's Most Wanted," it clearly stated the real Theater Thug was really violent, and a picture was shown for evidence. Because Josh never showed any traits or was dressed like the Theater Thug in any way, everything that occurred to him from other people is therefore unnecessary.
It seems weird that Helen would let the Premiere be robbed in broad daylight and did not think to install security cameras which would have prevented the robbery in the first place.
