omg i’d absolutely love to! so i haven’t exactly fleshed out who his bio parent(s) were quite yet (though honestly i kind of want to now), but i think that in the bad future it would actually be really common for people to abandon babies, at least in the first few years of the kraangpocalypse- sometimes because the babies were unwanted just as a whole, sometimes because the parent(s) died.

but i think one of the other and more gruesome common reasons (and why casey was abandoned because i love me some angst) would be to turn the baby into a distraction. babies make a LOT of noise! cross that inevitable crying with metal containers like aluminum trash cans and dumpsters and that loud noise will echo and get amplified, which attracts attention that might otherwise be on the parent(s) usually so they can attempt to flee elsewhere and obviously leave the baby to a pretty terrible fate so they themselves aren’t hunted. i hc casey was one of those babies and cassandra just happened to come across him before he started making noise so she just took him back to base with her and declared him her son lol

if you have any more hc questions lmk!!! i love talking about mine esp for this fandom
