I have no clue. Though it's always been kind of a thing that Harleen became a doctor at Arkham at a young age and right out of college, so... maybe? Eh, even that's a stretch. I feel like those ages should be reversed, if anything. If not marking Babs' age down to a 21-22 at peak Batgirl.

I mean, when I was playing Harley as Batgirl in two past games, I had Babs in her friend group in order to eventually set up future Bat dynamics. But, even with this being a world in which Harley was over a decade younger than Bruce and his ward, I still had Babs being the youngest out of her friend group. 

I don't know, the whole Barbara romance thing aside, that gif is weird.
