Yes is true, our favorite councilor Velarn have a mistress (what kind of we don't know) read about "Info Drone" if you don't believe me http://masseffect.wikia.com/wiki/Sh.....ow_Broker_Base

I guessing he have a young turian lady, I mean he is one of the most powerful people in the galaxy when he is a councilor and every young ladies love powerful men and I think he rather want one who know what turian man wants than what other races knows hehe

Turian councilor and the turian race belongs to Mass effect
