While Phil is discussing "smothering" vs. "sfathering", Claire walks to the island carrying a stack of mixing bowls and there is a full carton of eggs out. It cuts to Phil, and you can see her arms aren't moving. When it cuts back to Claire, she has an empty carton of eggs in her hands. In the next cut to Phil, she's placing a bowl down next to the carton as she picks up the carton with her other hand.
