Fishy Things That Rosemary Says and Does
- Rosemary tells David early on that parents may not really know their children, and it's not their fault if they don't. Once, she recalls, a neighbour angrily confronted her saying that her son Robert stole $25 from them. (Side note: Robert ends up taking $2,500 from Margot.) He creates a fake charity under her name to scam money from people. David asks her how she dealt with the situation. Rosemary replies that she pretended to play along with his scam, confirming that she did start a charity. Here, we get a sense of how she's willing to lie for her son. It's no surprise that she would go as far as help him cover up Margot's mysterious disappearance.
- David does some sleuthing on Margot's Tumblr and Instagram accounts, discovering that her favourite hangout spot is Barbosa Lake. He comes to realise that after taking off from the gas station the night she went missing, she dropped by the lake. Distraught, he calls up Rosemary, who asks him if he's going to the lake. Which, she shouldn't know because he hadn't told her anything about his findings at this point.
- At one point, Rosemary tells her son, "Sweetie, let me take care of this." Distraught, she tells David to butt out of the investigation because he's too close to it. Her son Robert lingers in the background with a nervous look on his face. It's possible that he's on the verge of spilling the beans about his own involvement in the situation. Additionally, Rosemary may be concerned that David might recognise her son as being one of Margot's classmates. Looking back, this seems too loaded a scene to dismiss.
