Arrow built up steam this week after an underwhelming mid-season premiere. "A.W.O.L." proved to be one of the show's stronger Diggle-focused episodes to date, allowing both the brothers and Lyla ample opportunity to shine. Meanwhile, Felicity's character arc hit a crucial new period and the show began to build stronger ties between the flashback storyline and the present-day conflict. This episode barely even needed Oliver Queen in the first place.
