Arrow may have teased Thea's (Willa Holland) exit before the hiatus, but the show followed through on her plans to leave Star City behind for good in "The Thanatos Guild," which will be Holland's final episode on the CW drama.
Thea and Roy's (Colton Haynes) big plans to leave When Nyssa Al Ghul (Katrina Law) showed up to ask for Thea's help taking down her father's new League of Assassins called The Thanatos Guild. Thea reluctantly agreed to help Nyssa find an all-powerful weapon Malcolm (John Barrowman) had tracked down before his death, but apparently not reluctantly enough. Roy was not happy to see Thea so easily side-tracked from their happily ever after, and he spent all episode griping about it. It all came from a place of love (and fear of losing her), but it caused a definite rift in the newly reunited couple.
Speaking of reunited couples... Nyssa was on her A-game tonight, brining up her "marriage" to Oliver (Stephen Amell) at pretty much any available opportunity, much to Felicity's (Emily Bett Rickards) chagrin. In the end, she agreed to officially annul that sham union, but we're 100% sure she spent the entire episode screwing with them first just for fun.
When Nyssa left town, however, she didn't leave alone.
Thea decided that rather than running away from the crime-fighting life, she needed to fight a bigger, more threatening crime. The "weapon" Malcolm had discovered was actually just a map pointing to the location of three more Lazarus Pits around the world. Thea is uniquely qualified to know how much hell those pits can cause, which is why she decided to join Nyssa on her hunt to find and destroy them, even knowing it could cost her, her happiness with Roy.
Never fear, shippers. Roy may have protested at first, but ultimately, he realized that he and Thea could live happily ever after wherever they went, whatever they were doing — up to and including hunting magical resurrection pits sought after by a secret society of killers.
If that's not true love then what is?!
