The back of the van smelled like stale coffee and Bill's cologne, which he insisted was called "Midnight Thunder" but smelled more like a gas station air freshener. Molly sat cross-legged on a crate, studying a crumpled piece of paper with the precision of a general reviewing battle plans. "So let me get this straight," Bill said, arms folded. "We're robbing a six-year-old's birthday party." "We're not robbing a six-year-old," Molly said. "We're robbing forty presents that belong to a six-year-old. There's a difference." "Is there?" "Yes. One sounds like a crime against children. The other sounds like a crime against Toys R Us. I prefer the second narrative." Bill rubbed his temples. "Molly, there's gonna be a bounce house." "I love bounce houses." "There's gonna be a clown." "I hate clowns, but that's not the point." "There's gonna be forty screaming children who will absolutely notice two adults stuffing Barbie dolls into a duffel bag." Molly held up a finger. "This is why we have costumes." She reached into a bag and pulled out two costumes, tossing one to Bill. He unfolded it slowly, horror dawning on his face. "Molly. This is a dinosaur costume." "It's a raptor. Very popular with kids right now." "I look like a green trash bag had a baby with a chicken." "You look like Rex, party entertainer extraordinaire, here to make balloon animals and steal literally everything of value in the backyard." Bill stared at her. "This is insane. Even for us." "Bill, we've robbed banks." "Banks don't have moms watching." "Moms are easy. Moms are exhausted. Moms haven't slept since 2019. We walk in, we do the raptor dance, we distract with balloon swords, and I sneak the presents into the van through the side gate." "And what if a kid asks Rex the Raptor to do a magic trick?" "Then Rex the Raptor learns real fast how to disappear." Bill groaned, pulling the costume over his shoulders, wriggling his arms into the sleeves. The tail dragged pathetically behind him, brushing dust off the van floor. "I feel ridiculous." "You look majestic. A predator among sheep. Well—children." "There's something deeply wrong with you." "There's something deeply broke with us, and this fixes that. Forty presents, resold quietly, no one's the wiser. Kid gets attention from a real dinosaur, parents get an unforgettable memory, we get rent money. Everybody wins." "Except the kid. Who loses literally every present." Molly paused, tilting her head, considering. "Okay, fine, we leave him one. The biggest one. We're thieves, not monsters." Bill zipped up the costume with a defeated sigh, his voice muffled beneath green fabric. "If we get arrested in dinosaur costumes, I swear—" "They won't arrest Rex," Molly said, grinning as she slipped on her own bright pink tutu, adjusting her fairy wings. "Especially not when Tinkerbell's giving out cupcakes." "You're insufferable." "I'm resourceful. Now come on, Rex. We've got a party to crash."
