Theory 1

I'm starting to think more and more that Aaron is, what Kenji called, a test tube baby.

Like it would make so much sense.

Juliette and Emma are obviously engineered to have powers, Evie says so in Defy me.

"I rewrote your genetic code."

It would also explain why Anderson doesn't treat Warner like a human being.

"He [Anderson] thought there was something wrong with Aaron - that there was something wrong with him on a genetic level."

In my opinion that's an extremely odd conclusion to make on your own, but if you literally custom made your kid's genetics it's actually a plausible excuse.

I imagine it would go something like:

Anderson: "Hey Evie. Did you program my son to fall in love with your daughter?!"

Evie:"Why on earth would I do that?"

Anderson:"Because they would obviously make the best, most handsome superpower babies ever."

Evie: "And have you as an in law? Likely"

It would explain why Warner looks so gosh darn perfect as well! Down to the dimples!

I think it would also make a rather nice final conversation between father and son.

Anderson: "I made you...! You belong to me and I won't let you rise up against me!"

Warner: "Dad, for f*ck sake, chill!"
