    Summary

    Inspired by CAS.
    Starting at episode 12: Everything is falling apart

    As the world falls apart, Leo becomes the leader of what’s left, carrying grief, sacrifice, and impossible choices on his shoulders, especially the loss of his twin. Years pass, hope thins, and survival demands more than anyone should have to give.

    Donatello’s death leaves no ghost, no echo, no hope of reunion. Only a silence so complete it fractures Leo from the inside out.

    These are the moments of grief during the three years without his other half.
