True, but I wasn't trying to sell it. First, that's something I'd seen discussed elsewhere (and perhaps here) and, considering there was discussion about how Howland and Ned were both there and how perhaps Jon and Meera were perhaps secretly siblings, my thought was "hey, wouldn't it be cool if...?" I think the biggest difference was I was always "R + L = J" first.
Yeah, I didn't care for the minor theory online of R + L = J & M. People went with it due to Meera having a similar age to Jon and same curly dark hair. There were no other clues/forshadowing to support that theory. It was also too similar to Star Wars.
