You hovered besides G-man, as he spoke to an engineer, but as the engineer went to leave, Astro Detainer warped in, grabbing the engineer and cursing him, before flicking him at G-man. He looked at G-man, then to you.

Astro Detainer: "I should have known that you would come crawling to him again....you always were a little lapdog for G-man. But atleast it saves me the trouble for having to find you. I have you both, together.*

He turns towards G-man, who is looking oddly....calm?

Astro Detainer: "You of all people should know, the penalty for treason, commander.....no-one escapes, justice."
