Ted and Cassie, the recently singled girl from earlier, try and enjoy a trip to the nearby lighthouse. The conflict between Robin and Loretta resurfaces.
This episode provides examples of:
- Chekhov's Gun: The toy car Cassie slips on can be seen on the stairs in several previous episodes.
- Rapid-Fire "Yes!": At the lighthouse where Ted proposes to The Mother, she couldn't contain the joy enough that she interrupts him with a "Yes!" multiple times. It takes several attempts before she lets him finish the question.
- "The Reason You Suck" Speech: Lily loses it and lectures Ted about how no girl will ever fit his perfect criteria.
