The other characters are getting their own Clan V now.

Clan Solus, and I think I saw a Clan Zorah. (I joined Clan Solus, by the way.)
I don't think Garrus will become like Saren either... and I like Saren, so I'm not just saying that because I don't want it to happen. xD He might be more Renegade if Shepard keeps encouraging him though. I just can't see him with a vengeance against an entire species and putting people in danger on purpose, but I think he could become the type who wouldn't care about killing people like Harkin.
@Ragabul: Now that you mention metal under his bandages, I wonder if we will see Saren-stye cybernetics on his jaw/mandible. I've been wondering if Saren had them from an injury, since they're on the cover of Revelation before his Sovereign implants. I guess if Garrus takes his bandages off in ME3 and has something similar, I can assume that's the reason Saren has them.
