Jack Knife ran out of equestria, he is on the run in a country call The Other Place, or Top. He does one job somewhere, then leaves. He doesn't know why he is running, or who he is running from. All he knows is that somepony he didn't know was killed, and all she said was to run. So now that is what he does.

Stopping means death,

Running means Life.

But somethings change.
