Alias

Look closely: After Vaughn and Lauren return from Mexico and Vaughn confronts Jack about their ordeal, Vaughn pushes Jack against the wall and threatens him. When Jack pushes Vaughn away and walks out the door, you can see the reflection of a boom mike operator in the glass of the door.

Number 47: The gizmo Sydney uses to open the vault, displays several numbers, at one point you can see the set "471318".

As with many American TV shows, this episode shows a certain stereotype of Mexico -- the police are unshaven and look like they haven't taken a shower in days, and the jail is a rickety shack, for example. And also, like most American shows, they employ actors who speak an unidiomatic Spanish and with an American English accent. The scenes in China, by contrast, show well dressed and clean shaven Chinese soldiers, these actors seem to speak a rather decent Chinese, and they also show a rather sophisticated environment.

Vaughn seems to have recovered from his near-fatal stabbing very well in less than three weeks...
