You convinced Wayne Haas to let you into the morgue.
As you have to come to the station to get to the morgue for your main mission, so this is the time to obtain this achievement. It also helps with the 'Motherly Ties' and 'Sentimental Value' achievements. Seeing as if you enter anywhere without speaking to Wayne first and him letting you in, the police in the area will go hostile.
As you enter the police station head to the front desk and make your save here. Now speak to your old friend Wayne Haas. You and him go way back but he has some demons haunting him that are stopping him from letting you inside. While talking to him choose the following dialogue options:
In some cases, you can choose Absolve for all. If it doesn't unlock the first time try this route.
It almost seemed like his responses had some randomness to them. I was told to come back later, so I reloaded, and the SAME conversation menu selections had him moving away from cooperation. Lucky for me I picked up the influencer augmentation...
if you use the casie aug and use the pills against him he's waiting for you in the lobby of the chiron building towards the end and tries to kill you. But if you just do absolve, crush, absolve, absolve he'll let you through and when you meet him in the lobby use absolve, and you offer him a job and he doesnt try to kill you
