"Aza! Where are we going?" Alvaro asked looking at Aza who looked so angry. Then he tried to hold Aza's hand. "You should be able to control your emotions because many people are after you."
Aza remembers her grandmother's words so she can control her emotions. She also heard Alvaro's words trying to remind her not to get emotional. She didn't want many people to know her true identity. "I need to be able to control my emotions because I don't want anything to happen to any of us."
Alvaro seems to really take care of Aza. He was always there for Aza because they were both brothers.
Aza really loves Alvaro more than anything else. Even he was willing to die to be able to save Alvaro's life. For him Alvaro is a life that cannot be separated from him. "I promise I will never get emotional with anyone."
