Trojan Horse (гет)

For Kathleen Stabler, the holidays mean war. She has been fighting a decades long battle against her father, with no end in sight. But this year? This year, Katie has a trick up her sleeve. A trojan horse, if you will. A trojan horse consisting of a beautiful captain and her adorable, blue-eyed son.
Yeah, he'll never see it coming.
(Or: Elliot keeps eating all of Katie’s Christmas chocolates. She enlists Olivia to help her retaliate.)
