Upon Thea Queen and Laurel Lance turning up in Nanda Parbat, their arrival just so happens during a Nyssa and Malcolm sparring session. What was fantastic here was a throwaway line from Nyssa as she welcomes Thea be calling her sister-in-law. It was a moment that may have been missed by some, but this was obviously in reference to the marriage that took place between Nyssa and Ollie as Season 3 came to a close. Seeing how well things are going with Felicity, it might be time for Oliver to dig out those divorce papers.
