Around a year after Jason has been resurrected he still wanted to get his hands on Bruce Wayne and the Joker. To get his revenge.

But after Joker dying and Bruce dying, he went back to being a vigilante. Red Hood.

He was on patrol that night, word Harley Quinn was out and about with Poison Ivy. So, he took the West side of Gotham City, watching the streets below. He then caught sight of Harley and Ivy. But just as he was about jump down to apprehend them, he paused.

There was a third woman with them. She looked exactly like Harley, but her smile, albeit way less creepy and more cute, it was Joker's smile.

"The fuck..." Jason continued to watch them. It obviously showed Harley and Ivy were taking this mysterious girl out for some late night shopping. There was still some stores open.

And since no cops were chasing after them...they obviously paid for their clothes.

Jason stalked across the rooftop as they went into a diner, getting their evening meal.

Jason didn't report in the other girl, he just reported Ivy and Harley behaving and just getting dinner for themselves.

Jason would have a closer look at this when he got back to the Batcave.
