So what happened to Breen?
I personally believe he was transferred into an advisor’s body. Think about what happens in the EP1 advisor room; a video in which Breen specifically mentions, and agrees to, being put into a host body. (the devs had to have put it there for a reason) Then an advisor appears, is apparently afraid to let Gordon and Alyx see him, and launches an unprovoked mental attack. Futhermore, when you meet that same advisor again in EP2, (he’s the Barn guy) he is apparently inexperienced with his advisor abilities.
It just makes sense to me, but I could very well be wrong, and that’s what this thread is for. Proving me wrong.
