7 0 0As all achievements, this achievement is story related, No need for a guide if you don't like spoilers. Note: this is one of the longest episodes in the game. *** Spoiler - click to reveal ***Alfred will come and visit you. He's got a reason to get you out, depending on your choice earlier. While driving in the car, Harvey will call you and say that you've made a wrong decision. You'll get stopped by a police checkpoint. The guy wants to search your car. Some angry people will attack your car and the police guy offers you to let you pass in return for a small donation. You can also choose to let Alfred ram through the barricade. I you chose to let Selina stay in your manor in the previous episode, you'll now see her say goodbye. After that, you'll go to the batcave with Alfred. Lucius will be there if you invited him to work for you earlier. Examine the drug molecule and the clean DNA at the batcomputer. You'll need to modify the drug molecule. Match the molecule to the one on the top left. For me it worked like this:Move the bottom one to the right twice, go up once to switch to the middle piece. Rotate that one once to the right. Go up once to change again. Rotate that twice to the right. Grab the antidote and inject the cure into your arm. Your lead is Vicki Vale's parents' house. Inside the house, walk to the left to find a body. It's Mrs. Vale. Investigate the entire scene so you can link some pieces of evidence. Link the syringe to the neck wound. Link the knife to the lock of hair. Link the logo to the family photoLink the wall intendation to the belt buckle. There appears to be someone else in the house. Scan the stairs to find a little boy, the one from the picture. First, calm the boy down. Then asked him what happened. One of Penguin's drone will show up. Some QTE will result in you taking out the drone. Officer Gordon will show up. After some short conversation, this chapter is over.
