Wendy has known Thomson since first grade and has always been good friends with him, unlike all of her other friends that she frequently hangs out with, who she's only known since freshman year of high school. Wendy hangs out with Thomson alone all the time and only drags him along when with her other friends (he is extremely intimidated by Robbie) because he is their only method of transportation. He's always the first to realize that she has another relationship budding and the last one to say "I told you so."
