Oliver is the first to realize that attacks on Lois and Chloe by a dark Archer, rather resembling him, are the work of his archery mentor, Vordigan. Chloe's research later puts Clark on his trace. As Oliver feared, the loner-rules of the ancient Cletic society they belong to make his disciple Mia the next target. Clark catches up during the archers' final duel. Meanwhile Zod is determined to use Tess's knowledge of Clark's secrets.
