Denial, anger, bargaining, depression, and acceptance, as my friend @emenai2 had noticed, were feelings following us (and Isko) through the discovery that our Isko is actually the one responsible for the fire. Most of us got stuck on 2nd one. In the end, I accepted it, like Isko.
I will write my feelings regarding the matter and how I got to the 5th one. At first, I denied his involvement in the matter. Then, I felt anger mixed with denial throughout the 3rd to 12th ep... I believed he was used by Kenan. Sadly, subsequent episodes dispersed such notions.
Then I started bargaining and blame it all on Celebi (thinking maybe C actually did it, to keep Iskender in check), or that Isko is covering for someone (his mother), or anything but the simple fact which he himself has stated, and I kept believing that, until the 25th episode...
When Iskender told the story to Cicek that his only goal in life was to one-up his brother, to prove to him he is better than Celebi gave him credit for. Then, I got depressed, because I understood his motivation for his stupid acts.
Before moving onto acceptance, I will mention why we rarely saw Iskender outright admit his guilt but we often saw him describing that event as an accident, or bowing down his head in compliance. He had an enabler, Arzu, who always retracted his guilt with the word 'accident'.
So, finally, when the finale came... I, as Iskender, fully admitted, there is no magic salvation, he did it and he will be punished for it. Now, even though throughout the show he never outright denied his involvement, he never came to terms with the severity of his mistakes...
In a way, Cicek freed him from his inner torment by making him face his actions and accept his punishment, because, sadly, I don't believe he would be able to do it himself. At the same time, she gave him hope and a reason to survive it. A similar progression can be seen in C&P.
Unpopular opinion... Bak, you all know that I adore #iskenderkayabeyli... But I honestly believe it was a plan all along for him to be the culprit. I believe Burcu had enough opportunities to exculpate him if she wanted... But she didn't. I'll probably do a thread about this...
Exhibit A: Iskender's behavior when Tomris says, how does it feel to play with my grandson knowing you killed his mother.
He is turned with his back. He swallows deeply, closes his eyes... And only then he turns around and counter-attacks her. With: Peki... But what about you?
This is remorse... This is regret... This is guilt, so wonderfully portrayed by our darling #berkergüven. Iskender is a human. A human who made a horrible mistake. He never denied he had something to do with it. He always said it was an accident. And in his mind, it was.
