Who did it?

In Matthew's private mansion where Zion and Katherine were staying…

Zion jogged down the stairs with his phone in front of his ear.

"Yes, Dad. I'll be attending Mr. Xi's declining health. It's classified information." Zion said as Zachery called him about Zion's sudden arrangement.

"Yes. I'll be staying here for a little while." Zion nodded, walking towards the kitchen to grab a glass of water. "Yes. I'm fine. I'm sorry if this is a little sudden. Alright."

Zion talked to Zachery on the other end of the line like usual. Surprisingly, Zachery didn't get mad about it. Well, his son was attending the Xi Family. Why would he get mad for such a  fiasco that befell the Kwan General Hospital?

"Thanks, Dad." Zion said before hanging up the call. Just as he did, he jolted upon the loud shattering noise coming from the living area.
