Why do people think Terra is a GOL?

[Jermaine 79]

I don't think he is because of that line you stated in DDD, and also because they seemed to outline the 7 in DDD. I take what the game gives me, and speculate off that, not make blind assumptions. But in the trailer/interview, it seems they could be drifting from the motives set in DDD, so we'll see. Terra would be #8 on my list, so if any guardians laid out in DDD, aren't actually guardians, Terra's next in line..

I think people here are forgetting the ling will. He can be a gol too.
