Nomi and I have only met Robbie a few times, but he impressed us as a dedicated, fun-loving kid who was mature beyond his years. Last I knew, he was studying to become a physics teacher, which makes him ever nearer to my heart for obvious reasons. I actually Tuckerized him in a story, "Pedagogy," as Robby Greenberger, the principal of a school that hires an alien to teach science.
Robbie, we all know you can beat this thing, and that you're going to come through just fine. Good luck; we're all rooting for you.
