A great, almost-all explained penultimate-of-the-season episode 1.7 of The Rook last night, in which we learn how Myfanwy knew she was going to lose her memory, and in turn why she wrote that note and left other information for her future amnesiac self, and how specifically she got into that position with no memory on the bridge, surrounded by a bunch of dead guys.
The episode is one long flashback that begins with yet another EVA with another kind of power. It's someone for whom the month ahead or longer can seem but a split-second present, in which the EVA can see all these future events. Myfanwy has discovered her, and she tells Myfanway that Myfanwy will have her memory wiped, by someone under the sea.
We already knew that Farrier was responsible for Myfanwy's memory loss, and Myfanwy discovers that, too, when she sees Farrier standing under a picture of the sea. Farrier's reasons are not completely bad, maybe not bad at all. Erasure of her memories of Checquy is the way that Farrier can let Myfanwy leave the organization and have a normal life, which is what her sister who talks to Farrier wants.
The guys on the bridge were killed by Myfanwy, whose uncontrolled EVA power manifested when two groups approached her, and she had just lost her memory. Afraid, confused, she reflexively protected herself from the groups which she saw as would-be attackers.
Meanwhile, earlier, we get a steamy scene of Myfanwy with the Gestalt, which explains the relationship see has had with them in the previous six episodes.
All in all, a very nice piece of work, with leaves open only one really big question: what will Myfanwy do in the present, i.e., the way we saw her at the end of episode 1.6 last week? See you here next week, after the season one finale.
