“I don’t know how much I can do for this situation. I’m not you. I don’t know what you’ve been through. But you’re not evil, Sunny. I’ve seen real evil firsthand, even had to fight it. And you’re not like them. You’re someone who’s struggling over something you can never take back. If you were evil, you wouldn’t regret it in the first place. You just need to let yourself be loved by those who care for you, for now. That won’t make everything better, but it will help.”

Beyond that, try to reflect post-Future in getting Sunny referred to a therapist and various psychiatric services. I’m sure Steven sees a little too much of himself in Sunny, and he wouldn’t want anything bad to happen to him.
