I think the EP's said this. But in reality and this is taking in the media frenzy post the finale. It seemed ALL of the media reviewers saw that it was Felicity that brought him out of his darkest hour, not Laurel. That scene between Oliver/Laurel was seen as unmoving, considering that Oliver did not react until Laurel stated that Blood knew about his mother's death. Fine. But everyone, and I mean from media to audience, took note of Felicity stating that she believed in him in the Clocktower. Ultimately, the media even stated that Felicity was his "moral compass."
I think what I'm reading is that people are putting much weight into the words of the EP's during a particular episode. While the media, which is actually something that Guggenheim, Berlanti, and Kreisberg watch and read, could not speak enough about the Clocktower scene or the mansion scene. Ultimately, the scene with Oliver/Laurel was lost and critically not given ANY recognition by the media. Actually when that episode aired, people spoke more about the scene between Oliver/Felicity/Diggle in the new lair than about Oliver/Laurel.
Honestly, I think the writers and EP's are trying very hard to make Laurel relevant, but she is continuously trumped by not only Felicity's character...but the depth in which EBR goes in her scenes and delivery. For instance, when the EP's were staying that the scene between Laurel and Oliver in the early mid-season episodes, were a blimp...no one talked about them. But people spoke about Felicity/Oliver/Barry Allen and they spoke about the Felicity scenes in the Time of Death episode. Ultimately, people hinted heavily that EBR is amazing at doing drama and comedy.
As I said, this is to see where Laurel fits and what works, and every time they try something they hit a wall.
