After Tess left for her date with Tim, Maria called Mrs. Moreau to tell her that she'd need to see her that night. When it turned out that Ben and Maria both had plans, they argued about what to do about Benjy. Meg offered to watch Benjy for them, but they weren't enthusiastic about the idea. When Meg asked if they didn't want her to watch Benjy, Ben reassured her that he just didn't want her to be forced to spend time alone with him until they'd gotten used to each other. Maria left, accidentally leaving Mrs. Moreau's card on the table, and Ben picked up Mrs. Moreau's card and took it with him. (thetvdb.com)
