Hearing what Michael said, Lucas said decisively, "I will never let him off. Jace must die!"
It wasn't only because Jace regarded Lucas as his enemy and wanted to kill him, but also because he wanted to harm the people Lucas cared about to anger him. Besides, Jace's mother had been the driving force behind Lucas and his mother getting kicked out of the Hutton family back then.
With such grudges, Lucas would never let Jace off!
Michael saw the determined killing intent in Lucas's eyes, but there was nothing he could do about it.
The only thing he could do was not to let Lucas and Jace meet. Otherwise, one of his two sons would surely die!
Regardless of which son died, it would be a disaster for Michael, and he didn't know if he would be able to bear it.
