Curate, connect, and discover
Jason and Jade met on some mission before Jason went back to Gotham, and they continued to sometimes meet up afterwards as well. Mostly on missions, again, but sometimes Jade would just come up at Jason when he's having breakfast or something and they would chat a little bit.
Perhaps they, in some way, felt like kindred spirits. Both on a mission that they feel like they need to do, even if it's not necessarily all that they want out of life, but they also don't know if they can live another type of life, either.
Anyway a few years in, there's a knock at the front door, and when Roy goes to open it, Jade is standing on the other side, in civilian clothes and with a very expensive pair of sunglasses on her eyes and even more expensive bag slung over her shoulder.
"Hi?" Roy says. "It's not like you to come knocking on my door like this."
"I'm not here for you", Jade says (though it's not unkindly).
Roy completely understands.
"Lian's at Ollie and Dinah's", he says. "I can call them-"
"I know, I will come visit her too", Jade says. "But right now I'm not here for her, either."
"Okay?" Roy is now officially out of the loop, it seems.
"I'm here for business", Jade says, very unhelpfully, and then masterfully steps around Roy and into the house. "Bird Boy!"
Jason makes a sound from the kitchen, and Jade marches in there. Roy follows her, and steps into the kitchen just in time to see Jason hand Jade a cup of tea, and for Jade to pull out something wrapped very tightly in plastic from her bag. It makes a very loud thump as it hits the table, and Roy realises very quickly that this is going to be a very long day.
