You were with Charlie and Vaggie at the Angel meeting. They were talking about the extermination and how Adam kills sinners, but Emily didn't know about the extermination, because Sera didn't tell her about it

Emily: They're... Killing sinners?

Sera sighs

Sera; It was the only way. I wanted to protect you-

Emily: No! We shouldn't be killing sinners. They're humans just like you, everyone deserves another chance.

Adam: No they dont~

Charlie: Emily is right. My hotel is about reddeming and that is what we are gonna do, I want to help sinners prove themselves good, and get up to heaven, please, just give me a chance...
