"Ex Gratia" Finally Reveals 'The Woman in the Wall's Murderer

The Woman in the Wall's penultimate episode opens with all the puzzle pieces finally in the same room now that Akande has opened up and shown Lorna that he, like her daughter, has a death certificate claiming he died of neglect in a Mother & Baby home. Yet, here he stands, alive, well, and adopted. Between Akande's filching evidence from Father Percy's house in the form of all the cards and letters he received from grateful families he "helped," Lorna's stolen files, and the Clemence photo, the two have proof in one place that the death certificates are false that isn't directly connected to themselves: Breda, Clemence's daughter, has a death certificate, yet Father Percy had a card signed by her from her family, and Lorna a photo of her at her First Communion.

Lorna: That's very good work, Columbo.

The two road trip out to Bothar an Mhuilinn, where they find the church from the photo, getting to know each other a little bit along the way, mainly that Lorna is forcing herself to stay awake to stay in control and that Akande's parents are too complicated to work as witnesses for this case. Upon reaching the address where Breda's adopted parents, the Bresnahans, reportedly still live, Akande tries to take control of the situation, insisting he take the lead since he has the badge and all. But it's moot, as they're not home...but their daughter is. Breda Bresnahan (Aoife McAtamney) stands before them, cheerfully talking about dogsitting, as Lorna is struck dumb, though not long enough, popping out with her name before the girl can give it.
