Either way, someone’s going over that line. The writers didn’t set up that plot device for nothing. 😉
But that’s what has me worried. I hate when writers make characters lose their memories. It’s such a cheap plot device to defuse tension and replace it with silly drama. However, I’m going to reserve judgement until I see the actual episode. One of the characters losing their memory might add to the story, and that’s what’s most important.
