Harry is in critical but stable condition (at the moment) with a very rare respiratory thing. Initially they thought it was pneumonia when he was rushed to the hospital last weekend, but it's far worse than that. No real root cause, but the outcome is literally 50/50. Past 24 hours the high-dose treatments have apparently helped with some improvement, so the positive thoughts and/or prayers certainly won't hurt.
His family and very close friends do appreciate it.
