Arrow Season 4 Finale: 12 Big Questions We're Asking After 'Schism'

Darhk's daughter, the Daughter of Darhkness, is returned to her father this week, although it's not enough to stop him from trying to go ahead with his world-ending plan.

However, while he emerges from the cave and fights Oliver (and ultimately dies), she isn't seen again, which begs the question of what exactly happened to her? Is she taken in by authorities? Did she die? Or is she biding her time, taking on the power of the idol, and waiting for the right moment to strike back against the people responsible for killing her parents? The likelihood is we'll never find out, but maybe it's worth remembering on the off-chance she returns to fight Oliver as a revenge-driven magic-wielding monster in Season 7.
