Laura first appears in Sebastian's point of view when he enters his home for the first time in the movie. She tells him that he needs to get a life, to which he responds, "I'm letting life it me until it gets tired. Then I'll start hitting back. It's a classic rope-a-dope!"
She again appears later with an engagement ring on her finger.
Then she appears for the last time at her engagement party where Sebastian is playing the piano.
