Adea told Emma that Chris was her partner in a scene. After they started seeing each other, she found out that he was engaged. He supposedly proposed to Adea because Chris claimed to leave his current fiancée, Mary.
She was asking where to buy red candles because she may have wanted some for Chris’ uncle’s funeral, which was in Sacramento. What’s funny is that this is the first mention of Adea’s weekend plans and of Sacramento.
Remaining anonymous, he speaks that he is unsure if he’s the last person to see Adea leave, but he states that she appears to be scared of someone else, not of the ones who were in the truck. It turns out, he didn’t write down the license plate number.
