I don't know even what to say... Look on humans! Some of us are very high, some are very short. Some have hair growing on faces in high amounts, some have hairs growing on their backs in high amounts LOL XD Some humans have widow's peak on their lobes, some not... Some have hairs growing on their fingers, and some are just bold everywhere....... In my opinion it is better TO TELL US SINCE WHEN SAREN GOT THOSE PIPES! They were present before he got upgraded by the Sovereign! In addition, his Geth arm is probably and artificial limb which replaces his destroyed arm. In my opinion, he got severely damaged in some battles and I think that our best friend Drew Karpyshyn MUST WRITE a book, or even better, create a flashback DLC for ME2 where you play as Saren and find out what HAPPENED! O_O O_O Isn't it awesome?!
