Just supposing the coincidence that Damon lived in the same town that John Walsh's child disappears from, wasn't such a coincidence.
That the disappearance of Michel Nigrete (whose father was a co-worker of Damon's) wasn't a coincidence either.
THE IRONY. That John Walsh has Brenda and Damon on AMW to help them recover their own child.
Perhaps Walsh has suspicions concerning Damon.
