Imagine a fanfic where Jason had run into Tim a few times when Tim was just a wee little stalker boy and they had a few talks or whatever.
Timeskip to when Jason is red hood. He goes to attack Tim!Robin w/out knowing it's the same little kid. At some point during the fight Jason realises and has to take a few steps back because. . . Anyways, Tim, being the maniac that he is says that he just wants Jason to speak to the rest of the batfam, because they miss him or whatever. Jason refuses but after a bit of pushing (not that much) he agrees to take Tim back to his house.
Jason helps Tim heal up and makes him promise not to tell anyone about his new roomie.
Chaos, fluff and angst ensue
