How is Zaynep's graduation speech connected to episode one?

In episode one Zeynep asks herself if someone’s destiny is decided by his or her mother and the house where he or she is born. She seems very doubtful and worried about what she can expect from her future life.

During Zeynep’s graduation speech the viewer understands how much she has grown by the fact that she thanks both her mothers, despite their opposite cultural and financial background.

Another important element is the presence of Zeynep’s dead brother who wanted her to study and become a lawyer. She finally kept that promise and realized her dream.

She gives a special word of thanks to Mehdi, who supported and never judged her despite her past life.

Zeynep’s graduation speech is an answer to the worries she manifests in episode one; in fact, at the moment of her diploma she understood she wouldn’t become who she was without all the people she thanked in her speech.
