I read Ken Corday's 2016 interview about DAYS' declining ratings. As far as I'm concerned this happened for two reasons:
1) The complete misuse of vets.
2) Aging characters without knowing what to do with the new teen scene.

My story starts in August 2015, around the time of Serena's murder.

She was in Kyle's apartment, watching as he gaped at the open safe. "You think I'm an idiot, don't you, Paige?"
"No, of course not! I don't know what you're talking about."
"You think I don't know that JJ is hiding right behind the counter about to turn me into the Feds. I really don't want to hurt anyone, so it's a good thing this will be painless."
JJ slumped to the ground. "Paige…"
"NO!"
"Paige, wake up!"
Paige Larson tried to even her breathing. As images of her bleeding ex faded from her vision, she focused an unsteady gaze on her worried roommate.
"Daphne…did I wake you?"
"Nope, I just got back from that party across campus. I would've invited you, but you've been kind of MIA lately."
"Right," Paige sighed. "So, why are you back so early. I mean, it's barely after midnight."
"Not soon enough, there was this drunk jerk who couldn't keep his hands off of me. Look, if you're sure you're okay, I'm going to get ready for bed."
"You don't need to worry about me, " Paige assured. "But I have plenty to worry about," she thought, as the shower began to run in the next room. She wondered who had the unpleasant task of cleaning up after her mother before she born. Mostly likely, it had fallen to Grandpa.
"That's it!" Paige snatched up her cell phone.
To GRANDPA: SOS! Mom's at it again, and I think somebody's in trouble this time. Big trouble!
