On Valentine's Day after school, Carolina, Truman, and T.D. are going to visit Helen and the four of them are discussing their cards. At Helen's place, it's revealed that even the dogs got sent Valentines, and that Carolina made a card for herself with a recording of her singing (badly). While the kids and Martha talk, Skits tries to get their attention, but they brush him off.
The kids and dogs go outside to play in the snow, and then T.D. gets the idea to make more Valentines. They go in, but accidentally leave Skits outside. The girls and T.D. start working on their Valentines, while Skits looks for attention again, Martha talks to T.D., and Truman seems dubious about the whole thing. Then, Carolina's glitter pen goes missing and she asks T.D. if he took it. When Helen goes to look for it, Carolina sees glitter on her hand and thinks Helen took it.
While T.D. and Carolina go to look for the glitter pen in the kitchen and Helen searches upstairs, Truman goes to start on his Valentine, but he seems worried. He eventually admits to Helen that he's afraid of craft because in kindergarten, he accidentally glued himself to the table, and he's afraid he'll glue the scissors to his head. Helen tells him to just draw something.
Meanwhile, T.D. and Carolina are still searching for her glitter pen. However, when Helen comes up to tell them she couldn't find another one, they try to pretend they were just playing with Skits. When she leaves, Carolina still thinks Helen is the thief, but T.D. thinks that Helen would never steal anything. Then, he sees his notebook gone, and Helen reappears and tells them that her fabric is gone.
The kids and Martha start searching around, except for Truman, who just writes. Then, Skits comes up and claims (in barks) that he has something to show his friends, but it turns out that he just wants the kids to throw more snowballs. They go back inside to find out that Carolina had written a Valentine that read, "You stole my heart and T.D.'s notebook and Carolina's glitter pen and Helen's fabric." She explains that it was in order to make the thief confess. T.D. bars everyone from leaving the room, but Carolina feels that that's her job, since she thinks he might be the thief. She considers telling everyone's parents, but then Martha reveals that she knows who the thief is.
She takes everyone into the living room and interrogates them. Truman reveals that he did look through T.D.'s notebook for inspiration to help him overcome his fears, but that he didn't take it. Martha has Truman lift the couch cushion, which he does, revealing the art supplies. Then, Martha reveals that it was Skits who stole the art supplies, since he hides things there, T.D.'s notebook has his slobber on it, and he did it for attention. The kids reassure Skits that they aren't mad, and they all go outside to play.
