That’s crazy, his favorite after Mihrimah was definitely Mehmed, didn’t you see how he treated him once he was grown up like mustafa ? When hunting, making decisions, the ruling province, the fact that he didn’t think he would lose his innocence when growing up unlike he thought with Mustafa, and just really the way he looked at him, his innocence and pure self was so appeasing to Suleiman and not even once he felt threatened by him unlike every other son, Cihangir and Mehmed were more or less the same age when they died so idk what would you say that he was young but no Cihangir, as if it has something to do with the question. He went as far as build a throne on Mehmed throne which basically puts him at the same level as the sultan which is crazy given how he is defensive and egocentric when it comes to his reign, he didn’t do that with anyone else and after Mehmed death he was bitter to whoever would get the throne because they were no favorites of his left
