In the movie Synchronic Brianna is sitting down on a stone during a birthday party and there's an inscription carved in the stone that says "All ways" (or "Always", I can't remember).
At the end of the movie, we know it was not written by her because when Steve says he saw her message she replies "What message?"
We see that
when Steve arrives to rescue Brianna, there's no carving in the stone. Since he stays behind...
So I assumed he carved it, but is there anything in the movie that would imply it was him? Does the writing have any meaning to any of the characters?
