--- EDIT: scratch that, now I'm really having doubts as to what I've seen, due to streamer quality (stutter and lag). I'm no longer sure about whether it was

Spoiler:

a bio component Jiart saw that made him pause - or something completely different altogether.

But one thing is certain, Theoria was shown at that moment, so it concerns her in one way or another.

-- EDIT bis:

Spoiler:

Just double-checked with 2ch's screencaps. With their armor/cockpits breached, it looks more like Jiart and Izuru were able to look each other in the face, which means Jiart might have been stunned by the revelation of what a human looks like (remember Nadesico? When humans finally got to see what the Jovians truly looked like - and what the implications were?).

The "bio component" I saw seems to actually be Jiart's translucent cockpit.

EDIT ter: I've completely misunderstood the scene, it seems.

Spoiler:

The bio-mechanical part I saw on my crappy streamer was definitely Jiart's cockpit, not Red 5's internals. And Izuru realized Jiart looked like Theoria. Still a bit unsure as to WHY exactly Jiart looked so dumbfounded - maybe it WAS the realization that humans look like Wulgaru and vice versa? It could also be because Izuru practically destroyed Jiart's chestplace - which covers the cockpit-...a feat he didn't expect from his so-called prey.
