Chapter 10- Homeless
Midway through the chapter when you're all sat down eating. Walter will ask you how you are different, answer however you like. After doing so press up on R3 immediately as this is your only chance in the chapter to unlock this trophy (I didn;t get it until my third playthrough).
Talk to Tuesday and check on her baby. Talk to Jimmy and use Aiden to heal the 3 areas of pain. And use Aiden to channel Stans deceased wife.

it's very important to channel Stan last, because if you do his first or second, it goes straight to a cutscene and ends your chance of helping Tuesday or Jimmy.
