16. The Thanatos Guild

Complete story — includes the ending

Nyssa al Ghul comes to Star City for Thea, claiming that a splinter group from the League of Assassins, The Thanatos Guild, led by a woman called Athena, is coming for her to get the location of a map that Malcolm Merlyn supposedly knew. Thea reluctantly agrees to help Nyssa, but claims she is leaving afterward. Team Arrow eventually finds the box containing the map and uses mathematics to unlock it, only for the map to be blank when opened. Felicity helps to reveal the hidden markers underneath and discovers that it contains locations to other Lazarus Pits. Dinah grows suspicious of her superior on the force, suspecting that she might be peddling Diaz's drugs. Thea talks to Oliver about handing the Green Arrow mantle back to John, but Oliver worries that the current circumstances may be a little too much for John at the moment. Thea, Roy, and Nyssa eventually depart to destroy the Lazarus Pits and Oliver says goodbye.
