Going back to the underground/ant hill in Inglewood/colony of little ones idea.

This is all just speculation and connecting possible things( as per my usual)

Going with arts idea of ant-apes with a certain amount of night blindness. Lets piece together how this scenario could work.

Say the little ones did come from underground. With the sensitivity to sunlight they would have, keeping them in dark areas would he paramount. We loosely can assume that the little ones were in the basement at the hospital. We can also "loosely" assume that one of the first hunting trips they went on was at the base when kalani and angel first encountered them. While not an underground location, it is a dark, cool quiet place.

Now, knowing what we do about the basic behavior changes of the zoms. Could we not assume the same would be true for the little ones? Could not their growth,intelligence,strength,etc be attributed to that? I mean, that we are aware of...the only other ones to show physical "growth" are the behemoths. And whether or not that is artificially done is up for debate. So I have to question if the little ones were ever human. Much as what is said in the show. Also, who's to say that there isn't more of them still at ground zero if that's the case?

I dunno, pretty crazy shit...if you actually let your mind wander down the side roads.
