They are all demons, right?

I'm slightly confused over who was speaking and if Cash didn't see Luke erase the number off Matt's hand, how does he know only one person has his number? Did he give Matt the wrong one?

I just made Chocolate Tapioca Pudding for the first time and had to sample it a lot to tell when the tapioca was done and get the flavor right (I had to fiddle with the recipe because I didn't have the right kind of tapioca) and now I feel overfull.
