Marvel's The Defenders: 10 Ways It Sets Up Daredevil Season 3
9. Elektra's Return (And Demise)
Admittedly, Elektra wasn't handled all that well in The Defenders. Her sudden remembrance of her previous life came with an equally sudden turn to villainy, and while the twist that she'd been playing The Hand all along would've made for a good one if she'd - y'know - killed them all, her motivations remained unclear right through to the series' end.
While it's likely that Elektra isn't actually dead (the character has a habit of returning a lot in the comics), it's important to remember that her comic-bound death immediately preceded the events of Born Again. It weighs heavily on Matt, as it did in The Defenders, but it's still unclear as to how it'll impact another solo season.
She will, inevitably, make another appearance somewhere later down the line. While it could come in season three, expect Marvel to sit on this one for a little longer. The character's been killed off enough for now.
