There was a twitch that even an Eldar would struggle to notice due to it's speed and microscopic scale, but nevertheless Epsilon had it in his right eye when he was mimicked. However when the man revealed he had the mask - and was disrespecting the item - it was much more noticeable with his head cocking on one side for a millisecond before returning to it's original position. His equipment seemed intact, but he was nevertheless distressed. Unused parts of his brain flared trying to tell him something, something to do with emotions, being taunted and the subsequent anger.

If you do not tell me your designation, your unit and why you are here on this ship, I will not torture you – torture would be redundant on one of your kind – I will imprison you.

He was quiet and did it hidden to all but the most attentive of eyes, but nevertheless the sharp and impeccable teeth were grinding hard. Whether or not it would yield, the Kriegsman would turn to the sound and lean in when it was seemingly the closest and say "No, he wouldnt...." before lunging out hoping to catch the counterpart with his teeth. All the while, he was howling "For the Emperor! Die heretic!" in unending repetition.
