LOL! I never got it for some reason... but I read that people said they never got him.
Well, how about that.
According to the wiki...
"If Shepard has not revealed the sabotage and tries to make Mordin abandon the mission while Wrex and Eve are both dead, persuade options can be used on Mordin to convince him that it is for the best if the Shroud remain sabotaged and the krogan fooled into believing the genophage cured. This is the only scenario where Mordin lives. Both Mordin and Wiks agree to fake their own deaths, but Mordin becomes a War Asset at the Crucible project, whereas Wiks, according to an e-mail he sends you after the mission, instead seeks out a quiet colony world where he will work as a farmer and take his secret to the grave."
Crap. I'll never finish the game twice more before Inquisition.
EDIT: I actually did fulfill those requirements the last time I sabotaged the genophage (before this one), but Mordin died on the SM. I did get that e-mail from Wiks.
