Katie, jealous of Taylor's friendship with neighbor Viv, reluctantly competes in the Westport Halloween Zombie Run after she finds out they'll both be running. Meanwhile, Greg and Anna-Kat get a little too much in character for the zombie part of the run's obstacle course.

Katie's least favorite holiday is Valentine's Day, but her desire for a low-key approach is overridden by Greg's over-the-top romantic gestures. Meanwhile, Oliver has an expensive gift for the girl he's crushing on.
