Capítulo 553: 8.14.5 Dark history of Blood Heart Family.

Hearing the name Wortham, something clicked in Amir's mind. To this day, he never really knew Duke's first name as he mostly went by his middle name, Wortham. Though it wasn't that odd to him, considering how commonly used this name and title was. 

But now that he thinks about it, why was there no first name of Duke, why did he go with Wortham and not the title that suits him more as the protector of the Royal family? 

Such questions kept pouring into Amir's mind before he asked a somewhat stupid question.

"Foster sister? Was she adopted into our family?" A question whose answer came to his mind the moment he asked. 

The name his Grandfather spoke of was Emilia Wortham, without the addition of Bloodcrow, meaning that she was never adopted into their family. So why was she called Duke's foster sister? What and how was this relationship formed?

What happened for him to borrow the last name of his sister as his middle name?
