Arrow is plotting a mother of a reunion for its 100th episode.
It’s anyone’s guess how Moira will reappear — when last we saw her, she was being killed by Deathstroke — but given Arrow‘s affinity for flashbacks, it’s probably safe to assume we’ll be seeing a past version of Oliver and Thea’s mother. Or given that the episode falls during the middle part of a crossover with Supergirl, The Flash and Legends of Tomorrow, Moira’s appearance could happen via time travel or another Earth.
Thompson will next be seen recurring on NBC’s Timeless, premiering Monday at 10/9c.
Arrow Season 5 premieres next Wednesday, Oct. 5 at 8/7c on The CW.
