"I haven't had the chance to ask you about your mate. How did you meet Flynn? And when and how did get together?" Adrien waited for Flynn to leave Magnus' room just so that he can stay with his brother alone and ask him about his mate.
Hector was also there because Adrien keeps asking him to stay with him wherever he goes but he somehow felt like he has to leave the two princes alone.
He glanced at Arthur who smiled when he heard his younger brother's questions "Well, almost a year ago, one time I saw him while he was walking out of the school that used to work in and going to his house when I snuck out as I used to do to go to the castle."
There will be a flashback to what happened between Hector and Adrien.
