His goodness put back a little of the faith I had lost. My grandchildren put back the rest.

- "Air Apparent": Don Flack making amends with his sister and helping her get a job.
- "Nine Thirteen": Jo encounters a man who's looking for her on her day off. It turns out Jo's departed sister was an organ donor, and the man was the one who got her heart. Jo then spends the day with him, and the man comments that when woke up after his operation, he saw a face he didn't recognize, which he thinks was Jo's sister.
Jo Danville: It's strong... it's beautiful... thank you.
- And at the end of the day, Jo asks if she could listen to his heart, and he allows it.
