Ruby caught up to their mark.
They usually prefer faster, cleaner kills than this, but shit happens.
Sometimes a target gets away while the guards occupy them for a moment.
Sometimes they just get spooked and run.
And of course, sometimes the shot or knife misses.

But Ruby always catches them in the end, whether it's an assignment from the Queen or just a side job.
It's rarely ever personal, bud. Luck just ain't on your side.
