What the Hell?

I had a question that Atomisk and I have yet to figure out. I was hoping if any of you can help.

Alright, so me and Atomisk were RPing on synergy, and at the last chapter of Hl2, I seen some green huge beetles walking in a strait line. They were inside the citadel, just before Breen's office, while riding in those pods. I knew they were there before we played synergy, so I asked Atomisk when it popped in my mind. He said they're the advisors, before I pointed them out, but you only see the first advisor in episode one (at least, I think.) Then I showed him them, and he said something like, "What the hell?" or "Those are not the advisors..." (I can't remember.) Bottom line: He was confused.

So, If anyone has any information about the green beetles, please let me or Atomisk know.

(Or maybe it'll be discussed in Hl2 episode three!)

Thank you. -Echo

Yeah i was totally fucking confused dude.

They're known as mortar synths, people theorized that they'd show up in the episodes but they haven't as of yet.

Acualy i belive he said "huge green beetles" sience when where mortar synths huge beetles?
Anyway if you're talking about that ones i think, those are called CrabSynths.
And it's the same deal as with the mortar synths pepole hoped they would show up in one of the episodes but have not so far..
