Bunny: Cass ran away after she killed as a child. What if she’d run into Addie? Addie was a mother, and a pretty good one. After Grant died, with Joey living with the titans, Addie was grieving. And then during one of Searcher’s Inc. jobs, one of her men finds a feral, underfed little girl hiding in a woodshed. Addie takes to her immediately, and Cass to Addie.
Addie takes her in. Cass’s martial arts skills are immediately apparent, and since they can’t communicate any other way, Addie starts teaching Cass other related military skills as a form of mother-daughter bonding. Without the intervention of the mage who originally reset Cass’s brain, learning language is much harder for Cass. But she’s starting as a little girl this time, with Addie’s dedicated assistance, an actual speech therapist, and an entire extended family of Searcher’s Inc. employed uncles, aunts, and older siblings. She’s doing all right.
Slade gets introduced to Addie’s baby girl when Cass and Addie come down to New York so Joey can meet his little sister. Cass being Addie’s baby girl, Slade is fairly well adoring from the start. Addie does not approve of Slade interacting with Cass, but Cass has so much fun playing (read: sparring, and making Slade work harder than he does half the time at his actual job) with Slade that she reluctantly tolerates it.
Two possible branches for this plunny: Cute, and tragic
Cute version: Joey takes some time off to get to know his new little sister, and consequently manages to avoid getting infected by the Azarath souls from Raven, never goes evil, and thus Slade doesn’t have to mercy kill him. Cass grows up surrounded by her adoptive family, a happy, beloved daughter, and the unofficial mascot of the Titans. Addie never gets poisoned, she and Slade eventually become friends again, if not ever lovers again, and it’s fluff and sap ever after.
Tragic version: Joey and Addie die like they do in canon. Slade takes the newly orphaned Cass in, doing his best to care for her. Not easy with a little girl whose gone mute again, and can’t go more than a few days without crying. Cass is the heir to Searcher’s Inc., and the company employees are keeping it running until Lady A’s daughter is old enough to take over. Slade ends up going into partial retirement to raise his traumatized step-daughter, and Cass grows up with Slade, Wintergreen, and the patchwork family of loyal Searcher’s Inc. employees, knowing her duty is to take over her mother’s company, and determined to make Addie and Joey proud.
I submitted this to the bunny farm. I’m actually a little sad I don’t have the time to do it myself.
