Russell and Claire contact an overworked social worker named Linda Paxton to help reunite Allison with her brother.

Allison convinces Josh to take her to Barbara Manning to find out how Tommy died. Barbara tells Allison that her brother took his life. She tries to fill in some of the missing pieces but is finally at a loss to explain what led Tommy to take his life. Allison runs off and hitches a ride to the rail overpass where Tommy committed suicide.
