“I just don’t think you can with anyone you have history with and someone you really, really care for. It’s usually one to 100. They do really love each other and they’ve hopefully solidified their friendship and hopefully can grow off the base of that.”

Anatoly has an interesting power over him that I don’t know a lot of other villains — if any villain at all — has ever had. Oliver didn’t kill Chase for a very specific reason, because that’s what Chase wanted, but he tried to kill Malcolm, and he killed Slade once upon a time, and then put him away in prison, and then he went on this anti-killing thing, but he still killed Ra’s al Ghul and still killed Damien Darhk. Anatoly is this weird grey area of a guy that he loves and respects too much.”

"We [TVGuide.com] do know that Oliver's son William will play a major part in the season to come, meaning Felicity will have to face that issue all over again and deal with it head on in a way she hasn't had to before. If she can manage to push past it -- and if Oliver can juggle an epic romance with his new fatherly duties -- it's probably safe to assume some wedding bells will be in Arrow's future"

They [Olicity] have so much history together that it’s just a matter of when’s the right time? There’s a dynamic that cannot be ignored with William. Oliver loves Felicity — and I think he hopes she loves him — in a way that they will always be there for each other. It’s been five months since Lian Yu, so if it takes another five months, or another five years, then hopefully they’ll still feel the same way.

His character [Michael Emerson] is definitely going to be a bad guy and is a bad guy we haven’t seen on the show before, I think it’s safe to say he’s really going to give Oliver and Felicity in particular a run for their money. He’s very soft-spoken. He’s very intelligent. And all of that is different than any of the villains we’ve had on the show in the past.

"She refuses the team’s help for 75 percent of it... As we’ve seen before, Felicity doing that doesn’t always end up in her favor and is also nearsighted. It has to do with stealing some tech. It is one of my favorite episodes ever. I had one of the best times filming that episode, so hopefully, you’ll like it.”

Oliver’s doing his best, but obviously he’s learning on the fly. This is not a situation where William went from an infant to a toddler to — he’s on the verge of being a teenager now and Oliver has had to step in. William has also had to deal with seeing things for the first time in his life that would traumatize anybody. So Oliver is doing his best, but William is a reluctant participant, so to speak
