Update

From Jim:

"they had to have emergency operation yesterday as they found a blood clot, as well his swelling started up again bad, so they rushed him in. He got out of operation about 7:30 pm, seems to be stable now, again back into waiting game"

And after receiving the above e-mail, I talked to Bob and he said Roy opened his eyes a bit and squeezed Julie's hand. So there may be reason for a bit of optimism.
