Kate--You go, girl! I'm hoping this will be a breakthrough for her--both seeing Marc now, and opening up to Toby.
I agree that Madison is being unrealistic. This is the career path that Kevin is on. It's not news. Many, many actors make it work, shooting films all over the world. Clearly, he's willing to pay any amount of money to get the best possible help/care for his family. Besides, even if he were shooting on a lot, 20 minutes from home, it doesn't mean they would see much more of him--he could be there 16 hours a day. And for a lot of actors, it's feast or famine--up to your ears in this project for a month, then home for 4.
As to the Laurel angle, this is what I'm thinking--she tells the hospital that her baby died, that's why she OD'd, out of grief. She does this because she's afraid, if DCFS finds William and the baby, he'll be lost to foster care. She hopes that William and the baby will be okay, since William is clean. Of course, this still doesn't explain how nobody put together the abandoned baby and the OD who just gave birth.
