When Cisco is attempting to put the Bomb on Kathy and she resists, she is handcuffed with only her right wrist. The other cuff is handcuffed to the clear leg of a table. After giving up on making her wear the bomb, Cisco places the bomb back in the cabinet. As he turns back to Kathy, both her wrists are now cuffed, and the chain is placed behind the table leg, not cuffed to it.
