I guess I'll post this here too so it doesn't get buried in waydrn:

Good news! I got another update from Kate (Witt's wife):

It's closer to his doctor and roomier than our place. Right now he's still sick, but the new donor blood isn't causing any problems yet which is a good sign. He's been under heavy medication and every time I've seen him he hasn't been awake. I'm told the scans they run on him are showing good results as in no more pockets of blood forming in his brain or circulation problems, so he'll be well on the road to full recovery soon enough
If anyone wants to send a card or something let me know and I'll give you the address she gave me. Obviously I'm only going to give it out to people I know well enough.
