Slade – “What is happening to me?
Oliver – “I don’t know, but I’m not going to let you go through it on your own.”
It’s really hard to recognize that things are changing within you and not know what is going on or what to do about it. Oliver’s response is perfect. What Slade needs is not some long, biochemical, or physical explanation for the changes that are happening, but rather someone who will stick with him through the changes and through the fear. I wish we could say/do this for each other more often in real life. Practically, however, it is a very difficult thing to do. Maybe attempting to stick with Slade was part of Oliver’s strength building that was required for him to become a hero.
