Tough

A firemen went into a coma after he was hit by a falling debris. He had a wife and a 1 year old son.

After 16 years, he woke after he was accidentally dropped from the bed. His wife after years of grieving, has moved on, remarried and is now pregnant. His 17 year old son sees him as a stranger. I was wondering how is he's gonna;
1. to deal with the 16 year gap
2. to rehabilitate into the world again
3. to survive without any friends

This was from last night's Grey's Anatomy. Anyway, he suffered a cerebral(brain) blood clot and needed a surgery but didn't make it through. In many ways I think it was a blessing for him.
