Hogan is full of it, as usual. Problems were brewing between him and Linda before the accident took place. Pretty sure the accident wasn't what alienated his daughter from him. Cheating on her mother with her best friend.....well, we might have something there.
And the accident came about because Nick is, to quote Bischy, "a spoiled rich fucking twat!". Who spoiled him? Who used their celebrity status to convince mark police officers not to issue speeding tickets? Who let Nick not only get away with reckless driving, but encouraged it, until the accident?
The family disintegrated under Hogan's watch, not that Linda doesn't deserve half the blame (hey, she's looking for half the assets, right?). To blame the accident for your family's break-up is typically shallow and self-serving Hogan BS.
On one point, however, he's right. The Hogan family's problems pale into insignificance compared to what the Graziano's have to deal with.
