I agree that in feeling that I missed the reveal. I'm also confused. At the end of the final episode, she was radioing in, announcing herself as DCI Marcella Backland, calling for backup and an ambulance to the Maguire estate. So is she done pretending she's dead? And if so, why was she still startled at someone tracking her down at the airport. And at the very end, the baby looked a couple of months older, so where had she and the baby been hiding out? Will her family find out that she's been alive this whole time. Frustrating, but then again, this show always has been.
