I politely disagree. I have seen the two faces of a meth addict. It's like Dr. Jekyll and Mr. Hyde. When sober, a person can be kind and thoughtful and loving. While high, that same person can be evil, paranoid, violent, full of rage. Especially someone with mental instabilities. Comparing Emily's book in picture to her recent court appearance picture, you can tell how clear her face has become. Meth can give you the hallowed cheeks, sunken in eyes, paleness, etc. Her current picture shows her face full and healthy. IMO, she was on something. Meth is the only drug I know that gives you that look. And if she was on meth then it very well could have been part of the reason something happened to Lucas. It may not actually help Lucas be found but it definitely helps us to get into her mind a little from a drug users perspective.
