Timeslip - Season 1 Episode 24 The Day of the Clone - Pt 4

As Liz and Simon pass the time chamber room, Simon realises that Liz's bracelet is still in there. They must retrieve it otherwise Devereaux and his people will know they have been in there. Luckily for them the time chamber door is still open and they enter the regency-style room. Liz hunts round for it and sees it dangling on the back of a chair. Before she can pick it up, Simon grabs her. He reminds her that they were hiding on the floor when it was lost. Why is it now on the back of a chair?
