"Arrow" Photos Tease A "Schism" in Season Finale

The fourth season finale for "Arrow" is titled "Schism," but whether that refers to a metaphorical gap forming between members of Team Arrow, or a literal rupturing of the ground beneath Star City remains to be seen. Oliver does look a little frustrated with Diggle in one photo, though.

What we do know is Damien Darkh's plans for Green Arrow's hometown will come to a head, and whatever the outcome, it's sure to spell trouble for Oliver and his friends.

The finale's synopsis also teases a "surprising force" helping Oliver out in his battle with Darkh, though who -- or what -- that is remains a mystery.
