Saren with two pistols?

That looks awesome! And I agree, his bandana is awesome. He's the only turian I've seen with one, and he's been wearing them at least since he was 18.
SpoilersYou're right, it's probably some type of Reaper language. (Can't be Prothean because it makes husks.) Desolas' line about knowing how to talk to them did suggest that Saren didn't know how yet. But there he is, talking to them not in the special language, and they respond anyway. xD
I don't think Saren's been effected by the artifact yet, but TIM definitely has and I get the feeling his brother has too. I'm curious to see how much, because if the transformation turns out to be something terrifying in the end, I doubt Saren would be so fast to let the Reapers implant him. And I'm curious to see if Saren will get his cybernetic eyes and face implants during Evolution, by contact with the artifact, injury, or both (that thing shoots lightning).
