Connor knew very well that the other party obviously knew that Connor and Freya had already arrived in Porthampton. That was why they had threatened the Phillips family to deny their relationship with Freya.
They did this to trick Freya into thinking that she had nothing to do with Connor.
Connor knew that he couldn't make John tell the truth in the normal way, so he didn't hold back and started threatening him.
John was obviously putting on an act in front of Connor. He was well aware how terrifying Connor's power was.
During this period of time, their Phillips family had benefited greatly from the fact that Freya was Connor's fiancée.
If it wasn't for the special circumstances, John wouldn't have wanted to give up on Connor, his big backer!
However, after hearing Connor's words, John realized the danger.
If a person like Connor wanted to deal with them, then their Phillips family simply did not have the ability to retaliate.
