End of Ep.13, running into Ep.14. Slade would like a repeat of last night with Ruby. Unfortunately they have both already agreed that was definitely a "one-off". He finds her taking off her jewelry before going to bed.
Ruby first removes the right earring   Slade then follows Ruby to her bedroom
Then she removes her left earring   Just in case you were in any doubt
So now she's taken off both earrings, right?   Yep, Ruby's earrings have grown back on
