When John returned to town, we really did not see much of him at all. He tried calling Marlena, got the cold shoulder, saw what was happening to Brady, so was trying to help him get back to no alcohol or drugs, was not successful. Then when Theresa got him drunk enough to go to Vegas, marry her, and they came home, Brady was so out of it, she called John to come over. He did, was trying to help him, was sitting in front of Brady, but had told Theresa to leave them alone. She grabbed his arm, he shook it off, she fell, grabbed the nearby poker, whacked John, moved bodies, (Brady was passed out) called 911.
And so, John was in a coma for weeks and weeks, with Marlena never or hardly ever leaving his side, Brady sobering up, doing the same, Theresa worried John would come to and her lie would be exposed.
So.....here we are, John woke up finally, has been in rehab, but still determined to protect his son.
