The midseason premiere will see the new, leaner Team Arrow discover one of James’ well-kept secrets. As the leader of the enigmatic Helix hacker group, James lives in a world where information, more so than might, is a premium. If Team Arrow’s latest discovery is really that juicy, it could spell the beginning of the end for James.
