4x7 - Taxi

Louie becomes irrationally upset when he learns that his mother plans to marry an elderly Japanese man. Louie makes his mother miserable in an effort to thwart the wedding, but she still goes through with the wedding (a traditional Japanese ceremony), and Louie refuses to attend. At the last minute, Alex talks Louie into going, however, and Louie proclaims that whatever despicable act he might perform at the wedding would be Alex's fault for convincing him to go. When Louie is very close to wrecking the wedding, he has a change of heart and gives the couple his blessing.
