Laurel in a nice training stance as she and Oliver work out together. Oliver will be learning an entirely new way to live, says the synopsis, which we assume means he has to readjust his life to fit Felicity's new physical condition. He can do it!
Will you check out the guns on Laurel? I'm so happy to see her and Oliver training together. This should be a really nice scene, and hopefully they have a heart to heart conversation about life, as well.
