I’ve another perspective from this scene after we learned that the writers perceived Oliver as in love with Felicity at this point in the story and being aware of it.
Everyone on the team is speaking to him and then Felicity raises her voice and everyone stops talking and Oliver’s eyes fall on her and it was like the room stop existing. It’s just the two of them and the problem at hand. His eyes are glued on her and he only listens to her. She says go and he goes and doesn’t even look back. He has the blessing of the woman he is in love with, she understands what he needs to do. That’s give Oliver the strength to go forward. She is the force that inspires him to keep going.
This is beautiful and now I’m more in love with this scene than before.
