I have a new idea why Josy has a tear in her left eye in the preview.

At the end of EP10 we find out that it gets worse and that is while Heather and Tommy are arguing. What did Nick say in EP10 when Tommy got the mushrooms from Lily? That will kill him.
If there is one thing we know, it is that Tommy is not good at dealing with mental stress. What if the conversation between Heather and Tommy leads to him snacking on mushrooms again and having one too many.
What if Josy got a call that Tommy is in the hospital? Yes, they hate each other, but they have been step-siblings for years. Even Tommy hinted something in EP9 about how he cares about Josy.
