its 1am but
as far as we are aware, the objects in bfdi have always existed together in that grassy plane of existence. and they didn’t have anyone else, it was just the 20 of them. this is emphasized with stuff like golfball’s tips and tricks book being millions of years old and stuff. the bfdi characters only ever had eachother— thats all they would’ve known they’re whole life.
leafy breaks this mold a bit by being able to travel to yoyleland, but those were still the only people she ever knew. and even if she might be not the best-friend (example number one bubble) she very much cared for all of them. i could even say she loved them all to a fair extent, they were all she really knew.
and via one mistake made in petty rage, she loses everything she ever knew and her whole identity. her existence revolved around being friendly, about always being the nice one. and a thief doesn’t really fit that definition, does it? the only people shes ever known try to permanently kill her, people who she helped throughout the first season. she lost everything. it all falls apart infront of her
and she forgave them. and i believe that leafy truly is a good object-person at heart. even if she kinda is an asshole sometimes.
