   Summary

   Shawn and Lassie's vacation has quickly turned into a disaster, and now Shawn's doing the one thing he knows how to do best - running away.

   His father is hardly a sympathetic shoulder for him to cry on, even if that's what Shawn needs. But things with Lassie might not be as terminally broken as Shawn fears, if only he'll give him a chance.
