The promo photos of episode 15, The Promise, of Season 2 of Arrow which show Roy and Slade with the Queen family, were revealed by CW on Feb. 25.

Stephen Amell Talks Oliver and Laurel Relationship Based Episode 15 and Teases Epic Finale.

In the images Roy is seen with Canary, Diggle, and Slade with the Queen family, which could spell trouble for the Arrow team.

According to the recently revealed synopsis of the episode, it seems like Slade is still seething with rage because of the Mirakaru and might prove to be life-threatening for Oliver, if he thinks that he is to blame. Over the season it has been made evident that Oliver feels slightly reponsible for, and understands why, Slade's recent change in nature. And the plot might thicken as Oliver agrees to kill Ivo, at Sara's suggestion.

Here's the official synopsis:

"Oliver (Stephen Amell) is shocked when he learns that Slade (Manu Bennett) has come to Starling City. Back on the island, as Oliver, Slade (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."

In a recent interview, Amell also dished about another important highlight of The Promise, suggesting that the episode would also focus on Oliver and Laurel's relationship. After having recently watched episode 14 and 15 he called The Promise one of the best episodes in the series, pointing out a scene he and Katie Cassidy, who plays Laurel, share on screen. Amell said that the scene made him "incredibly proud" and that he was generally "blown away" by the episode.

The Promise will air on March 5 at 8 p.m. on CW.
