715. Go to Michelle's house. Knock on the door and Jason will ask about the help with access to hospital's archive. Michelle will agree to help this time. (if she doesn't, that means you need repeat the part at hospital at night, there Jason takes Kendra's ID and tries to enter archives in the 1st floor).
716. Next day come back to Michelle's house, knock on the door. She will tell you a bad news, that the new receptionist is the problem. Jason realise that he needs somehow to get rid of receptionist.
717. (Billy) After the school talk to Billy and offer him to "Swap moms for a day" ("Ask Billy about his day with Janice" must be done).
718. (Billy) After Jason eats the sandwiches, there will be option to "Let's go to the beach". Enjoy the scene.
I did 715 and 716, but 717,718 cant give me this option, any help please
