Pru helps Mark dig for information and ends up unearthing some dark secrets. Elsewhere, Danny and Ally are perplexed when they find another body while, at the shelter, someone's past is about to catch up with them.
When they were twelve years old, Mark, Pru, Danny and Slade were out together in the park. Mark's five-year-old brother, Jesse, was annoying them. They were mean - told him to get lost. Jesse ran away. He was gone. Never seen again.
Twenty years later, Danny - now a detective - learns some shocking news. Jesse's DNA has been found at a hug scene. He is alive and out there. Somewhere.
