Au where when tim is in his depression era and trying to clone Kon, guess who just so happens to have had his human half destroyed and his core is flying around without a solid body or form to try to find the resources to rebuild Danny, when it/he happens across an already constructed body, that doesn't have anyone using it, and isn't dead! Yeah it's biology is a bit different from their old body, and it's just a little unstable from not having a second DNA, but core can take care of that, and the biology is close enough, it has abilities like core has anyway!
And so just as his last attempt at cloning kon started signs of destabilization like all the others, and his heart cracked just a little more as he saw it, he just barely caught a glimpse of a blur of black dart at the case from the corner of his vision when there was a bright flash of green. when he was able to look back without spots in his eyes, the clone body has shifted back just a bit from where it had been in the middle of the tank, almost like something had bumped it, and he could faintly see a glow of blue pulsing from within the clone's chest, almost like a heartbeat, then before his eyes the signs of destabilization went away, and the vitals on the monitor started to change, slow at first then changing faster as they stabilized yet slowed, almost like the same beat of the glow, and the computer said the clone had become fully stabilized. Whatever that glow was, he didn't know, but it seemed to be the cause of this, and he would be thankful even if it wasn't truly Kon he would be getting.
