This is what I got so far:
- Steal his wallet & talk to him
- Agree to pay the money "you" stole from him next meal (4k$)
- Wait
- When he's home after dinner in mom's room check it out
- He will receive a call
- Search the computer for his name
- Talk to the aunt
- Wait
- Talk to the aunt again
- She will suggest a hacker
- Go to the computer talk to the hacker and agree to pay him
- Wait a day
- Contact the hacker
Then you have 2 options keep erik but he can't touch your sisters and will work for you or get rid of him.
1. Get rid of him
Go to the computer and contact his enemies. Next day he's gone.
2. Keep him around and help you out
Wait for eric to be alone in mom's room
Talk to him
Dialogue is pretty much straight forward.
