I'm suspicious of the lack of mention of a third brother. And really, Humanity is giving so many details (yeah I'm with Brooder on that), it's surprising there isn't a mention of him yet.
Does this mean my off the wall theory could be right?
KLC--Well, back on page 1, Humanity did say that, a year before he was born, his mother had been told that "she wouldn't be able to have any more children." That's suggestive of other siblings. (And would be at a time before the mother saw the meteorite, or whatever it was she saw.)
Xade--Converting positive emotions into tangible energy is more accurate than telekinesis in Humanity's case. The door didn't just shut from his thought but shut from the energy beam that he projected.
Let's hope that Savunn's sticky note commentary will mention that Humanity must have a good reason not to mention his other sibling,or if they even have a sister?!?!
