Continuity mistake: While Mike is cleaning out the armadillo's hay, just before he finishes the second one you can see the amount of hay in the bin is a few inches from the top of the bin. The next shot goes to a close up of him removing more hay but the amount of hay now in the bin is a bit below the top.
Continuity mistake: Van on the Blue Team is asked to leave Hell's Kitchen by Chef Ramsey and is shown walking out. Soon after, when the Red team is nominating team members for elimination, the camera shows Nick on the Blue team and Van's Head is in the shot. If he was just eliminated how could he still be in kitchen. (00:57:00 - 00:58:00)
