Since we took a look at Heath being right or wrong to leave when he thought someone else could be his father...
What about Nick leaving when he was bite by the wolf... He knew how much his family loved him and how hard it would be on them not knowing why he really left.. then he leaves it up to Heath to not only keep it from them, but to have to be the one to after 60 days go get him and bring him home.
Do you think he stopped for one minute and really thought about what he was putting on Heaths shoulders? The strain on the families relationship once the truth came out.... ...Not once in 60 days did he get a hold of Heath in some way to let him know he was still alive to that point.
Or did Nick at some point think maybe he should go home ... heck he had it free and easy he was not having to look the family in the face every day knowing how much they hurt.
Or what of the pain to Tommy and his mom should he die while with them???
