Okay I'm sorry but how do I increase Cassie quest all I can do is talk to her asking how long she has been here
There is a guard at the passage from the Newark slums to Newark itself. He demands a fee for passage (5 credits). If you do not pay him, but push him aside by force, or deceive him, he will shout threats after you. You need to take a walk somewhere, and then return and go through the same passage. Don's men will detain you and take you to his house. You will need to go up to the second floor and talk to Don. He will offer you to pay a fine (200 credits). You need to refuse to pay, and then offer to do hard work for Don instead of a fine.
Don will show you a photo of Cassie and offer to find her for a reward. You need to go to Cassie and talk to her (a new question will appear). After that, if you sleep in Cassie's house, she will disappear by morning - she will be kidnapped by Don's men who were following you. Returning to Don, you will see her. It is better to refuse the reward (500 credits). After that, you will need to save Cassie. To do this, first go to Fawn's apartment and talk to her.
