Haibara: "Hum… Yukiko-san…? I… I really don't think that…" Conan: "Mom, that's… stop making it weird-" Yukiko: "Oh, c'mon! Just one last pic, Shin-chan! You'll want the memories later, you know? It's your first Halloween date with Ai-chan as a secret couple, after all!" Conan: "O-Oi! T-This isn't a Halloween date, we're going with the kids-" Yukiko: "Aw, I can't believe you two already went and made me such a young and beautiful grandma…" Haibara: "Y-YUKIKO-SAN-" Conan: "MOM!!" Yukiko: "What, what did I say wrong? You two always treat the three little sweethearts like your love children, anyway… Of course, that makes them my cute grandkids! <3" Conan: "… You see, now? That's why I told you we never should have let my mother find out about us." Yukiko: "YU-CHAN!! Our son's being mean with me! And he's gatekeeping our cute daughter-in-law and grandkids again!!" Haibara: "Oh, I don't know, Edogawa-kun… She's a bit extra, sure, but… well, I think it's fun and… really nice too, you know…? Besides, if anything… aren't you a bit ashamed for selfishly trying to monopolize their cute daughter-in-law all for your greedy self like that, Shin-chan?~" Conan: "Oi-"
(Yukiko helped them with the costumes, only to immediately start gushing over their cuteness right after and impulsively filling up their candy buckets all by herself before they even left the house, entirely defeating the whole point of going trick-or-treating in the process. They diplomatically return most of the sweets to her and share the rest with the kids before going out, though.)
