Similarly to what happened when the Mafia and the Armed Detective Agency made an alliance to fight the guild, the ADA and the Guild have done the same thing this time to fight the Decay of Angels. You and Poe were partnered for an infiltration mission; something he was beyond nervous for. He was a master architect, an author; he wasn't used to being in on the action like this.
