Until They Fly

"You did WHAT?" Thorne couldn't quite believe his ears when he got the call from his nephew.
"They had it coming, Thorne. Someone had to teach him a lesson and stand up for mom."
"Is that what you think she wanted?"
There was a pause on the line.
"Hasn't she been through enough?"
"Nobody else did anything..."
Thorne sighed. Frank tried to take his sons from Deirdre after the divorce. So yes, he did have things coming... because the boys were loyal to their mother.
Unfortunately, Philip's way of sticking it to his dad was to seduce his new girlfriend.
