A young musician decided to take a chance at an open mic night and ended up stabbed to death in the bathroom with a nail file on Rizzoli & Isles Season 4 Episode 14.

But solving that tragic murder wasn't nearly as difficult as dealing with Frank Rizzoli Sr.'s return home.

Frank didn't receive the warm welcome he expected from the children and ex-wife he'd walked out on. Why come back to Boston now? A diagnosis of prostate cancer had him longing for home...and Angela.

Only Angela has moved on. She's happy with her new life and her new boyfriend Sean Cavanaugh.

Angela told Frank she'd always be there to help him because he's the father of their children but he should return to his new home in Florida and move on as well.
