MUFFLE'S PROFILE

I want to be able to have my character say different things depending on what choices the player chooses in the game.

For example:
>You chose not to kill Elizabeth
When talking to sister: "Elizabeth is nice enough."

>You chose to kill Elizabeth
When talking to sister: "I could care less about it."

Also being able to use a different faceset when he looks at stuff depending on choices. Like if he chooses not to hurt anyone he seems more innocent and kind, but if he chooses otherwise he looks mean and cold. I already have his faceset I'm just having trouble putting all the events in.
