Jose tries to get attention of Estela, but later he finds out that she plays a sport and says that he has won many times and that he wants to challenge her. After playing he figured he would not be able to beat Estela at a sport he has never played before. So, he was embarrassed that he lost and wishes to never speak about that ever again and maybe he should gain strength.
I won several times and I want to challenge you.
I beat you 20-0
Now that I lost, I wish she would stay away from me.
