Addison meets Ryan, the guy Amelia has been getting wasted with on a regular basis. Cooper suspects something is up after running into Amelia on the street. The word "taco" becomes code for drugs as the team chats about her situation with Mason in the room. There was really no need for the ruse. Mason says he thought Amelia looked like a druggie when he met her.
Amelia bolts out of her place when Addy tries to have a talk with her. She shacks up with Ryan in a hotel room, but must break into the office to snag a prescription pad when they run out of pills. The police catch her rummaging through a desk. Charlotte vouches for her friend, but she can't stop an out-of-control Amelia from running off with her prescription pad.
Everyone is worried about Amelia, especially Sheldon. There's good reason for concern. Ryan seems to have all sorts of ways of escalating her drug use. Amelia is truly shaken when she wakes up to a room full of strangers. These drugged-out losers have been taking full advantage of the lady with the prescription pad. Ryan boots everyone out, but only so he can get Amelia high again. This guy is bad news and Amelia is in bad shape.
