Destiny (2) - S1-E22
Other mistake: When Max heals Kyle's bullet wound, the blood disappears from Kyle's t-shirt, but blood from Liz's bullet wound in the pilot episode stained her waitress uniform and did not disappear when she was healed by Max.
Other mistake: Guest star Eric Stoltz is credited as Eric Stolitz.
The Legend of the Lost - S2-E4
Other mistake: When the bad guy at the start of the episode runs to chase Sydney and Nigel, his foot kicks the side of the large stone lid which cause it to lift up. If this large piece of stone was real stone it would not have moved at all from being nudged by a foot.
