Agents Of SHIELD Season 4: 15 Characters Who Need To Return
10. Felix Blake
Last Seen: Delivering the pivotal warhead to Giyera in the third season episode 'Watchdogs,' which saw Blake reintroduced to the series as the leader of the anti-Inhuman terrorist group.
After being nearly killed by Deathlok back in the first season, Blake's ultimate fate was a loose end that a simple appearance could've tied up and given closure to. Instead, the series opted to use Blake for something bigger, planting a familiar face within the Watchdogs and setting him up for a heavier antagonistic role.
Sadly, Blake's season three episode was a one-and-done deal, the character once again vanishing from the show despite the continued presence of the Watchdogs in it up to the present day, making him a loose end once again.
Whether the series gets renewed or not, it'd be a crime to not see justice get served to the character before it's all over, especially when actor Titus Welliver does such a good job being a bad guy, and hopefully he'll resurface sooner than later to illuminate what he's been up to since we last saw him before he gets what's coming.
