In fact, although Samuel and Ezra were uncle and nephew, Samuel had always felt that he was quite good to Ezra.
Since Pamela was his only child, he even treated Ezra, his nephew, as his own son. He even thought that if Pamela got married one day and he had no one to succeed him, he would let Ezra become the next successor once he became the helmsman of the family.
Thus, Samuel had never doubted Ezra.
Until now, he heard his daughter exposing Ezra's lies.
Ezra had obviously invited Lucas and Jordan to the Howard residence, so why did he keep denying it and deceiving him?
After Pamela exposed the truth and Samuel questioned him, Ezra couldn't help panicking.
In fact, when he had the guards block Lucas at the entrance and found that Pamela was also there, Ezra had had an ominous hunch.
