Stephen Amell has posted a new 3-minute trailer for The CW's DC superhero series Arrow featuring the Suicide Squad and Deathstroke. We also have a clip from The Promise, which has Sara predicting that Slade Wilson aka Deathstroke is going to kill Oliver and his family. Get a fresh look at what's to come in the remainder of the second season and read on to find out more about The Promise episode.

In the episode, Oliver (Stephen Amell) is shocked when he learns that Slade (Manu Bennett) has come to Starling City. Back on the island, as Oliver, Slade and Sara (Caity Lotz) prepare to take over the freighter from Ivo (guest star Dylan Neal), Sara pulls Oliver aside and tells him he needs to kill Ivo to prevent him from telling Slade what happened with Shado. Oliver feels immense guilt over the situation but realizes Slade's growing rage from the Mirakuru makes him unpredictable and he could turn on his friends if he thinks Oliver is to blame. Oliver agrees to kill Ivo and the battle begins.
