Jason Todd: The League of Assassin's Babysitter

Everything is normal in the Wayne Manor and the Batfam but what happens when Dick mentions Dami's mysterious sitter that the Demon Spawn spoke oh so highly of? What happens when Jason actually sticks around instead of running from the manor? and what utter confusion will the rest of the family have to endure when Jason's old babysitting habits resurface?

I pretty much suck at descriptions but i'll try my best. The point is that Jason used to be Damian's babysitter when they were with the league of assassins, right? it might've been a one time thing or something rarely occasional in the comics but i'd like to take a closer look into it and since i can't get any fics on Dami and Jason like this - imma write it.

Hope it's good!
