Ok, here's a glitchy little coda for everyone. I logged back in just now, called the contact Doctor Dream, and was awarded the Determined accolade for DA story arcs. I guess the "15 out of 16" description is temporary until you get back to your contact.
I still plan to go back and do it solo for the "Knows No Fear" badge DR_Mechano mentioned! I did get the Incarnate Rival and Buddy Cop badges.
Thanks to everyone for helping to enable my badge problem!
