But when Oliver and the Canary are attacked at the Queen mansion by a trained killer from the League of Assassins, she confesses to how she's connected with the nefarious group. Meanwhile, with Moira facing multiple counts of murder and conspiracy for her part in the destruction of The Glades, the Assistant District Attorney offers her a choice – plead guilty now and avoid the death penalty or take your chances in court.

Oliver asks Roy to help him find the Canary (guest star Caity Lotz).
DC Comics' Bronze Tiger and China White wreak havoc on the Glades.
