I mean Steamliner has been seen to be able to roam between Ouroboros and Earth as it pleased compared to others. So it's pretty easy to figure that the two Chemies just saw a kid, decided to have fun with him, and took him to Ouroboros for the heck of it given while they're fairly pure, still mischievous.

It's not that hard to really fill in the blanks when you put a bit of imagination into it. And on that last point, again, not everything needs to be explained. Sounds like you just want to be spoon fed super long explanations to satiate the uncontrollable amount of theory crafting you did to feel satisfied. And because they didn't do what you wanted, you've resorted to childishly calling out the writers and series for some reason. Very unfortunate.
