Warning: Spoiler ahead for episode 16 of Arrow Season 6, called "The Thanatos Guild"
Team Arrow has undergone a series of changes in Season 6 Arrow brought members in and out. "The Thanatos Guild" did not rejoin anyone but former assassin Nyssa al Ghul for some unexpected reason, and what she had to say led to a major departure from Team Arrow. Thea decided that the time had come to leave Star City behind and concentrate on a larger ̵
Nyssa appeared after discovering that Thea was targeted by assassins for her status as the daughter of Malcolm Merlyn. She teamed up with Team Arrow to recover a box of a map Malcolm Thea had left. Although it initially looked like the card was an empty piece of parchment, the truth became clear when Thea's blood dripped on it. The map revealed three sets of ley lines, which meant that Malcolm had discovered the locations of three Lazarus mines. Determined to correct her father's injustice, Nyssa took the card and intended to leave alone.
Thea was determined to make amends for her own father's wrongdoing, and she decided that she should go with Nyssa and help her on her mission. She left Team Arrow with Nyssa (who eventually annulled her marriage League of Assassins with Oliver), fortunately alive and well. Roy also joined Thea and Nyssa, unwilling ever to part with Thea again. The bad news is fans will lose Thea from the show; The good news is that maybe all three characters will return. Thea will not be gone forever, and she could very well bring Nyssa and / or Roy with her. Of course, depending on your point of view, there might be more bad news coming out of Nyssa's return and Theas departure. The way Thea left with Nyssa means that the history of the League of Assassins is still not over though it apparently ended a few times. If you're not a fan of this plot, you probably were not happy to lose Thea for it. Personally, I am always happy to see Nyssa, and if the act of the Assassins League must be continued for Nyssa, so be it. My problem with "The Thanatos Guild" is that it brought Lazarus Pits back into the mix. Arrow – and the other superhero shows of the Arrow Verse have a problem with not keeping characters dead. The existence of Lazarus Pits in the arrow verse means that deaths are less severe because we know that they will not be forever. The stakes are simply lower in life-or-death scenarios. Lazarus pits can become "death-free" plot devices if they are not handled properly; I just hope that Arrow did not overuse her. Who knows? Maybe Nyssa will destroy these newly discovered Lazarus Pits, as she made the pit in Nanda Parbat.
Only time will tell. Perhaps the departure of Nyssa and Thea is not really a sign that [Arrow Arrow plans to revive Lazarus Pits as part of the narrative, and only teased her because Thea needed a very important reason, her potential happy and happy to give up.
