Dr. Morton straightened his somewhat disheveled clothes, then looked at Yigol Foster with an embarrassed expression, and nodded, saying, "I'm sorry, Mr. Foster."
Don't underestimate Dr. Morton. He may seem like a delicate doctor, but he's also a master at using poison. Anyone who comes near him could be killed within minutes if he wished. His previous submission to Yigol Foster's captivity wasn't out of fear, but because Foster was a... distinguished guest of their young master.
Now that the young master had spoken, he could only be so unkind.
Though Yigol Foster was poisoned and thus unable to move, he could think and see. He could only watch helplessly as he was dragged back into the stone room, only to watch helplessly as Lucas gave a light 'hiss' before turning around, instructing, "He's so troublesome, put handcuffs and leg irons on him."
And so, Yigol Foster began his days in handcuffs and leg irons.
He was not used to it, extremely unaccustomed to it.
