Titus Hardie and his Boys sketches
Chucky and Tiffany are fluent in Japanese and have watched anime. I mean, have you seen the scene in CP3 when he said sayonora? Plus, Chucky and Tiffany both understood what Glen said in Seed of Chucky.
I think back then they used to watched anime back when they were both humans.
I like how they’re taking a religious horror take on Chucky. I think it may be a reference to Chucky canonically being Andy’s personal guardian angel in Child’s Play and Glen being called an angel in Seed of Chucky. Plus, I think they’re foreshadowing Chucky meeting Annabelle for the first time.
