Summary
The Adderall in her jeans pocket isn't hers—Josie swears it. But when the conversation shifts from drugs to depression, from "I didn't take them" to "I think about what it would be like if I wasn't here," Matt realizes he's in way over his head. At twenty-one, he doesn't know how to fix this. He just knows he can't lose her.

Summary
When Casey's truck breaks down on a deserted back road, he and Severide think their biggest problem is sharing a makeshift bed in the truck for the night. They're wrong. Something is watching from the trees, something else separates them, and suddenly their biggest problem is no longer who gets more blankets: it's a game of survival. By morning, one of them might not make it home.

Summary
“Matt, please don’t do this.” Kelly sounded like he was hurting too but for a different reason.
“Do what?”
“Hate yourself, think it’s your fault when it couldn’t have been.” The words were so simple, spoken like they made sense, but harder to believe.
“Please just stop Sev, I can’t do this, not right now.”

Summary
Kelly is glad Stella is going out for a girls' night with Sylvie while he is away at the arson program, even though it means his phone will be quiet for the evening. But when the quiet is broken by a frantic Violet calling to say Kidd and Brett are missing, Severide does the only thing he can: he calls Matt Casey and catches the first flight home to meet him in Chicago. They're going to get their girls back, no matter what it takes.
Meanwhile, Sylvie and Stella find themselves hostages in a battle that is so much bigger than themselves.

Summary
Auld Lang Syne: literally "old long since," interpreted as "for old times' sake"
A time of the year that usually feels so wonderful for Sylvie Brett feels like anything but wonderful with all the tangled strings in her life. Her paramedicine program's funding hangs in the balance, and one of the two best friends she's been in love with for years has fragile custody of two boys that could be challenged at any moment. Add in exes that circle her and her boys (they are absolutely her boys, she just has yet to voice it) like predators stalking prey, and it would take a miracle to put her in the holiday spirit.
Yet Christmas is known as the time for miracles to happen, and when family comes knocking, the possibility of stars aligning seem more likely than ever.
