Meanwhile, we now know that Ray has taken the place Oliver (Stephen Amell) initially took in Felicity's life. In recent episodes there was some tension, but Oliver has learnt to step back and move away, respecting Felicity's new lover.

Some of the friction on theis account between the two men was showased in the next episode, titled Suicide Tendencies, which revealed an Oliver Queen and Ray Palmer face-off. The scene is Diggle and Lyla's wedding and TVLine suggests that Palmer is also officiating the nuptials. The report also sources executive Marc Guggenheim's discussion about the episode. Guggenheim stated that Ray will "go about things in a very different way than the Arrow does. And he's not a part of Team Arrow. Right now, he's just a very smart guy in a very, very powerful suit. Oliver's definitely going to have an opinion, and the first instance of that will be in Episode 317."

Here's the synopsis for 'Suicidal Tendencies':

"Still weighed down by his last meeting with Ra's al Ghul (guest star Matt Nable), Oliver (Stephen Amell) returns home to find a new villain and his crew have started terrorizing Starling City - Michael Amar AKA Murmur (guest star Adrian Glynn McMorran), a man whose mouth has been sewn shut. Meanwhile, Laurel (Katie Cassidy) and Nyssa (guest star Katrina Law) bond over their issues with their fathers and Nyssa makes Laurel an offer. Thea (Willa Holland) is forced to come to terms with her father after Oliver brings Malcom (John Barrowman) to the loft to recover, and Lance (Paul Blackthorne) shuts out both Laurel and the Arrow. Dermott Downs directed the episode written by Beth Schwartz & Brian Ford Sullivan (#316)."
