Continuity mistake: Murdoch has just walked across the fire in bare feet when he is clubbed on the back with a rock. When he wakes up, he has shoes and socks on.
Continuity mistake: The whole start of this episode is exactly the same footage from S1E9 Holiday in the Hills. This gives rise to a small mistake when Frankie boards the plane. This shot must have been filmed years after the rest of the opening scene, as Frankie joins the A-Team only in season 5. You can see this when Hannibal catches the briefcase from Face: then the side of the plane has red identification lettering on its side. When Frankie finally boards the plane this lettering has disappeared, because it's another plane. (00:04:20)
