Ghost and Wednesday's Child

Lily and Ian have finally returned home with Connor, Sadie, and the newest addition to their family. Across the street, Walt and Danielle are settling into parenthood, and down the street Heather is no longer worried about a certain annoying ghost surprising her in the middle of the night. But the calm on Beach Drive doesn't last long. It isn't just the arrival of Lily's parents, or the surprise visit from Lily's sister, Laura, who has been in Europe. It's the woman who shows up on Lily's doorstep, young boy in hand named Christopher, looking for directions to Chris Johnson's house.
