In The Past by 60sec400

Basically, Bruce, Jason, Tim and Damian all get stuck in the past and meet the flying Graysons a couple of days before their fall, it’s very bittersweet. It’s not as cheesy as it sounds.

A Pointless Resistance by emavee

Bruce gets stuck in a time loop and the only way to break out is to stop Dick from dying. Takes places when Jason in robin.

All Roofs of Uncertainty by Kieron_ODuibhir

Slightly more Jason than Dick, but still lots of Dick. Basically during a big JLA fight in a city Jason stumbles on an injured Dick and stays with him as he goes to the hospital

Childhood Home by emmacortana

Has a little focus on a relationship on Ducks relationship with Bea Bennet but not a ton. Buts it’s basically if after Bruce kicks Dick out Dick left and never came back. He never becomes Nightwing. And he becomes a cop and starts a family with Bea and then Bruce finds home several years later. It’s pretty anti-Bruce, but not 100% against him. I just thinks it’s an interesting idea and brings some interesting character moments

no matter how you unbend by Squishychickies

After the events of Nightwing 93 (so heavy mentions of sexual assault and r*pe, no descriptions of it just talk about it) Dick is stuck in a toxic relationship with Catalina and Bruce comes and get him to take him home.
