Okay, imagine you have two depressed, anxious aunts who won't leave the house and also think you're dead so you can't do anything directly, but what you can do is send them lots of anonymous pies over the course of several months and spike those pies with a small dose of antidepressants. There's that.
I did the same for Ton when he was in a bad place, only he knew I was doing it. He also knows I'm not dead.
