Finally we come to a ramshackle house among the poorer quarters of the city, but one with a festive mood, celebrating a 13th birthday party for Adriana (Paulina Gaitan).As Adriana's mother is cooking, Adriana's older brother, Jorge (Cesar Ramos) comes home, bringing his sister a beautiful birthday present, a girls' bicycle. Adriana is delighted with the gift, hugging her brother gratefully, but their mother, Lupe, is skeptic; where did Jorge get the money to pay for the bicycle?

Vadim and Manuelo will be arranging transportation for the two through Mexico up to Los Angeles.
