It's the mother of all cases on Rizzoli & Isles Season 5 Episode 1, as a young parent is stabbed 17 times while jogging in the park with her baby son.
The missing child hits home for a newly pregnant Jane, who is being plagued by crazy pregnancy dreams. That nightmare was fairly intense. You could feel both the fear and the determination rolling off of Jane in waves…until she opens that door and sees herself in her mother's robe holding a baby.
Then she's completely confused.
