QUESTION

She prompted him to found The Church Of England

Haven't watched the show in years, which is odd to say - but I'd gotten wrapped up in online stuff in 2020, and my old laptop sucks at playing DVDs (got a desktop computer to be able to watch DVDs, but never use it - this show is the main one that I've thought of watching).

Anyway, from what I recall gathering, she seemed to be meant to keep an eye on him... maybe to monitor if he were broken or otherwise compromised - maybe in part for safety. But having her as his spouse made it easier for him to live a double life without being exposed. The safety aspect is questionable, because she never saved him - but the former and latter make more sense.
I also think she was bored, and loved Edward. She knew it wasn't the same guy. I believe she was the one who killed the tech guy so that they couldn't fix Henry and Edward - because she didn't want to lose Edward.
It was like the wife was a counterpart to the therapist - another caretaker... but unlike the therapist, she previously only got to experience one personality... and everybody seemed to love Edward.

It's ridiculous that they cancelled this show.
