Forum:Septimus and Shai'ra

In order to obtain a trinket from the asari consort, I have to complete the menage'a'troi between the asari, the elcor and the turian before speaking with the consort. But what do I do, when the old turian doesn't want to talk to me? The assignment doesn't show up on my list, no matter how many times I talk to the elcor.
