@libratio a murder on the polar express!
A train ride with complimentary hot cocoa would draw the attention of any adolescent and their digimon. Though, in the middle of their ride, an announcement cut across the PA system: a body has been discovered, and its up to the passengers of the locomotive to figure out who the perpetrator was before they arrived to their destination.
Naturally, this earned Daisuke's ire, "Can't I go one day being on this island without something happening!!"
"With that mentality, you'd be in your room allllllll daaaaay! We best find someone and build up our alibi, before we're suspected, dummy!" Chibimon did in fact have a point...
So, Daisuke jumped on the cushion of his chair to see who was behind him...And it was some woman...With an egg digimon...He thinks??? Actually, he's not sure. Adults having digimon partners wasn't exactly common, so who knows. Now wasn't the time to bug out about that.
"Hey, lady. You didn't see anybody super suspicious in our cabin, did you?" And, while Daisuke was busy sleuthing, that was enough for Chibimon to enact its ultimate plan: drink the rest of Daisuke's hot cocoa while he was distracted...Always works.
