You should give it to the Asaris sitting on the couch in Zakera Ward (one of the higher levels).
I only found one Asari sitting on a couch in the Zakera ward and it doesn't do nothing, doesn't talk, can't talk to it... I am near the end of the game I have done everything short of going through the omega 4 relay so that might have something to do with it or... I don't know... thanks anyway
