BIG NEWS: Jack is in surgery while the team works the case. I'm guessing this is carryover from last week's eppy. Viv is leading the team. Bummer note for MS fans, Sam is the one who is keeping watch at the hospital.
Diana recently got a heart transplant and is living as if tomorrow isn't guaranteed to her. Her parents want to convince her otherwise but even they know the odds of a donor heart lasting past 10 yrs.
She has recently become very interested in her heart donor. She inadvertently learns that it came from a 17-yr old boy and it floors her to know it came from someone so close to her own age.
There will be a lot of typical teenage stuff. Texting, parents bug, etc.
We learn that Diana is lashing out by trying to fit in with the cool kids and spreading gossip, cheating on tests, etc.
She somehow figures out the name of the person's heart she got so she goes to see the boy's family.
ENDING SPOILER: When she goes to the house the older brother is there. Something happens (missing) and he takes her by gunpoint to the bend in road where his younger brother was killed. It seems he had been driving drunk and that's why they crashed. He is upset that his brother is dead but Diana is alive because of it. He's mad she went to their house when he was just trying to deal with his baby brother being gone. She breaks down and tries to explain she was just hoping that knowing would help her deal. Viv and Danny arrive and they order Tim to put his gun down... End Pages.
