This discussion reminds me of watching the last season of Legend of Korra and people seeing signs of [SPOILER REDACTED. GO WATCH IT, IT'S A GREAT SHOW]. I thought they were reading too much into things or at the very least that it would never be made actual text, but it turned out I was quite wrong on that one. (Okay, so technically it wasn't text until the comics, it was just very, very blatantly implied in the show).
