My stepfather's been released from the hospital today
He's mostly recovered, though there may be some residual effects for a while. No way to tell, but hey, even if he doesn't get much better than he is now, he's already almost back to normal. May not drive again, depending on how things go and whether or not he feels comfortable trying, but we'll see.
Anyway, thanks for all the comments and messages over the last few days, everyone
