If you don't call your brother back, he'll just track you down. At least, he will if he's Oliver Queen. Felicity has traced Thea's location to Corto Maltese, and Oliver, Diggle, and Roy go to retrieve her. Diggle's also there to check in on one of Lyla's field operatives who has gone missing, Mark Shaw (David Cubitt). Diggle may regret getting involved.

While most of the team is in Corto Maltese, Felicity stays behind and adjusts to her new job and Laurel meets Ted Grant (J.R. Ramirez). See photos of what's ahead in the below gallery.
