   Summary

   An accidental kiss. A wormhole in the sky. A voice note goodbye. Six months after the singularity event, Central City's getting ready to celebrate its first ever ColdFlash Day. The question is, will they be honoring one hero on-stage—or two?

   Or: In 2015, Barry Allen has gotten used to being a hero, but he still doesn't know how to convince the man he loves that his feelings are real. Meanwhile, Leonard Snart has found a dubious loophole to live his third lease on life with relatively few strings attached. A power-hungry speedster and an immortal psychopath complicate everything.
