This achievement is earned in Episode 4: The Survivors,Scenario #5 - Bygones.
This scenario is entirely dialog. The way it is setup is Nima does alot of talking. Your first instinct is to keep hitting "Listen" because the other choices seem like they would interrupt her.
Instead you want to pick the choices that pop up that are not "Listen" or "Enough Talk". The dialog tree should be the following:
You and the island
You used to live here
Your name means
InGen displaced you
Spared no expense
It must have been hard
Were you two close?
Sibo?
A lot like Jess
You still blame him?
Atlanta
They changed your life
Your father must be proud
Sorry about the island
Blip.
