Wow. Well, that was.....quite packed.
So after the underwhelming passing of Amanda Waller, Arrow follows up with one of the most development-packed episodes yet. In short:
Nyssa breaks out with the help of her own faction and wages civil war with Malcolm's faction.
Roy returns. (Albeit temporarily)
Tatsu returns (Probably also temporarily), with Nyssa versus Katana.
Shado (sort of) returns.
Darhk's wife is running for mayor against Oliver. (The flier literally says "a better alternative" *puke*)
Thea's dying from resisting the bloodlust.
We meet a villain called the Calculator. Who turns out to be Felicity's dad.
Oliver and Malcolm actually have a friendly moment over agreeing to let Thea choose to die rather than kill someone to satisfy her bloodlust. (It makes more sense in a non-condensed version. Just watch the episode -_- )
Nyssa offers the Lotus, an herb that counteracts the effects of the Lazarus Pit, to Oliver. In exchange for killing Malcolm.
And Guilt Arrow.
Diggle should help Cisco come up with supernames.
