By the end of ep 19 human being is now at the top of the citadel and will likely posses breen next, and I just realised I don’t think we’ve seen a single cortical this entire series.
And in half life 2 we see the gortigaunts try and contain gman

So my theory is perhaps the vortigaunts will try and contain the human being at the citadels peak.

Any thoughts?
