I'm all ready finish the chapter 13. But there is 2 stars that I could´t get....
* Isaac don´t open the door at library at day or in his house at night so de 4th star it's imposible to get
* Evan at night also couldn´t be find...it supouse to be at residential area (I think that it's at Isaac's) . So this it is another 4th star I can't get
