The pitch-a-day exercise is good for a lot of things. One of them: showing me which tropes I keep coming back to. Apparently I really like thief characters. Like so:
THE EARTH TWENTY-EIGHT JOB
Tina can travel between alternate universes whenever she likes. So long as a version of her exists on a world, she can slide into that other Tina’s body and live her life for however long she likes. Even better, she can take anything she’s holding with her from universe to universe, which is really convenient for a professional thief.
Less convenient is the cloaked figure who has begun tailing her, not only on her world but whenever she goes. Or the fact that one by one her alternate selves are dying off, almost like they’re being systematically eradicated. If she can’t figure out who’s after her and why, the next Tina killed off might be her.
