Other mistake: The battle droids - including the commando droids featured here - habitually have two broad fingers and a thumb. So how can a commando droid squeeze itself completely into clone trooper armor without its broad fingers tearing open the gloves, since it can't separate its fingers?
Other mistake: Season 2, Episode 20: "To the Lighthouse" - In the flashbacks to the jungle, John is considerably younger. Sarah however, is not. Adults don't change nearly as much as a child would in the same time period, but this is a pretty big jump back in time. John is only a child in the flashbacks, putting Sarah in her mid to late 20s. Yet she still looks 35 and even has the exact same skin and facial structure.
Other mistake: We see the letter about Merlin being written with a quill. However, despite the length of the letter being written we never see the quill being re-inked. (00:08:20)
