Even with everyone telling me point blank what was happening after Episode 6, it still didn't register until Wright wanted to talk to them both and Shannon nearly went BSOD.
It's definitely not a speculation I'd ever, EVER, adhere to without the Chiru episodes. It's just plain silly. Even if it actually works out completely looking back knowing what we know now. But still, so silly.
Even if it's hinted at quite a lot of times, just hints that aren't apparent until you can even wrap your head around something as crazy as that happening.. This always gets me in retrospect:
