A brief lapse in Dick's memory leads to him trying to call Wally after he's been gone for three months. He didn't expect him to pick up. Post-endgame Birdflash.

Dick's running himself ragged keeping up his work as Nightwing while trying to hold down a day job as a police officer. Wally's tired of watching his boyfriend pull himself in too many directions at once. Birdflash, set in an indefinite future.

After the training exercise went wrong in Failsafe, Dick and Wally end up sharing a bed and a few confessions. Light Birdflash, potentially one-sided depending on how you look at things. Rated T because I'm a giant baby who can't deal with rating systems.

Dick takes Wally ice-skating for the first time, in Venice.

Dick shows up at Wally's house with a box and some news about his future.

All it took was Wally getting seriously injured on a mission for Dick to finally work up the courage to say "I love you."
