Other mistake: When Jenna teleports down near the end of the episode, she takes 3 bracelets with her. When they all teleport back up to the ship she still has all 3 bracelets on. Therefore Vila and Avon should not have been teleported up.
Suggested correction: Jenna has 5 bracelets with her, she's wearing 3 and 2 are in her hands. She gives the ones she's holding to Vila and Avon. However, Ushton and Inga decided to stay and not transport back, therefore, she kept the extra 2 bracelets on her wrist.
