jack as a toddler but also god would be such a little shit. like kids themselves are absolutely insane, probably one of the most humbling experiences but having your toddler also be god? they never get a moments rest. like after dean and cas had both told jack no snacks cause it's too close to dinner, he magically locks them in a room together before making the door knobs disappear. dean and cas both start freaking out for who knows how long before remembering oh yeah cas is an angel and he could just kick the door down. and they rush all over the house in search of jack before hearing little giggles coming from the pantry where jack is sitting on the floor, surrounded by candy wrappers and eating his nougat bars that they'd put on the top shelf for exactly this reason
or jack decides he wants to see uncle sam and aunty eileen and when dean and cas tell him no, he just teleports himself into sam and eileen's living room. sam eventually gets a call a couple seconds later that yes, jack is here and yes, he's safe. in fact jack has already cuddled up next to eileen and is somehow communicating fluently in sign language, despite still not being able to properly pronounce spaghetti
even better if jack wants to go see his mom in heaven. and the first time it happened he came back to dean and cas tearing apart the house and neighborhood looking to find him. now when he goes he either has to tell someone or he leaves a little drawing of him and kelly (despite having once found him reading vonnegut the only word he can sort of write is his name, so a note was out of the question)
whenever jack gets nightmares, he'll just teleport directly into dean and cas' bed cause jack is scared the monster will grab his feet as he leaves his bed or it'll get him in the hallway. this leaves dean and cas having to get up to some pretty creative solutions to spend time together (turns out a toddler/god is even more of a cockblock that a certain giant moose of a brother, who'd a thunk it)
