In Chapter 7, as Laura, use the syringe to knock out Travis rather than stealing his gun and shooting him. In Chapter 9 when Ryan is stabbed, don't pull the knife out, but use it to stab Bobby Hackett and accept Laura's bite to earn Phlebotomy. As Ryan, you need to shoot monster Chris Hackett at the end of the chapter. After Chris' death, Laura needs to agree to work with Travis by choosing the Suspicious dialogue option.
