Zayn has just come out of the treatment room for a woman who is very, very loved. Hearing his father's baritone voice that seemed unfriendly when asked about the decision to marry a paralyzed woman, Zayn couldn't be annoyed at this time.
After successfully getting away from the room, now back to talking to his father via his cell phone.
"Has Daddy forgotten what happened in the past when he disapproved of my relationship with Dewi and set me up with a woman I didn't love? Are you still dissatisfied with seeing my destruction? This is a miracle as well as an opportunity for me to atone for the woman I destroyed her future."
Zayn did not stop talking at length in order to make his father aware that decisions taken by restraining him and not agreeing with his choices only ended in destruction.
