Fans were left wondering if Nyssa will be coming back this season after she was put behind bars. Arrowshowrunner Wendy Mericle confirmed to TVLine that Nyssa will indeed be coming back as she has unsettled business.

"Nyssa's stories are far from wrapped up," said Mericle. "She's in Nanda Parbat, she's been arrested in the wake of destroying the Lazarus Pit, and she has a score to settle with Malcolm Merlyn. We don't intended to leave anyone hanging, including her!"

The next episode, titled 'Legends of Yesterday,' will air on Dec. 11 on The CW.
