but the best explanation for Cumberbatch’s “we weren’t engaged then” to explain why his pregnant girlfriend didn’t walk the red carpet with him in early October 2014 is: between whenever she told him she was pregnant and 4 November, she was likely mulling whether to have an abortion.
If you look at Cumberbatch’s September and October public appearances, he is clearly not a happy camper. He was utterly miserable when a month prior he’d been on top of the world. His reaction to the unwanted pregnancy probably factored into the possibility of an abortion.
If she’d walked the red carpet with him at the London Film Festival of The Imitation Game and then had the abortion, we’d have likely never seen her again, and people would have wondered what happened to his girlfriend.
Also, readers, keep in mind Mummy Hunter’s “you never know…watch this space” announcement to the tabloid The Mirror came smack in the middle of the “I know she’s pregnant but I won’t marry her if she won’t keep it” period: early-mid October 2014. Which makes her braggart comments even more vile. Diehard Cumberbatch fans have always been perplexed by what that phrase meant in this context: it likely meant “you might be seeing and hearing more of my daughter if she doesn’t abort her golden ticket, which is of course why I’m encouraging her to keep it”.
“We weren’t engaged then”: the only reason they became engaged was because she was pregnant. So he proposed when she decided to keep it. Simple as that.
