^Well for my pet theory to work, they'd have to be faking domesticity. It'd have to be a hive consciousness that somehow evolved to bypass the cybernetic implants. Yeah, I know it's unlikely, but it is a *pet* theory and I can't help that the concept of funny looking insects changing the galaxy though passive aggressive behaviour is something I find oddly appealing.
They certainly had plenty of time to evolve and if I'm right, they're even older then the reapers. I may be wrong, but I think there was a sideways reference to them in the conversation with Leviathan
. Oh, and did anyone else get a familiar vibe from that exchange? Like maybe we've seen something very similar
