Why is Dylan acting so secretive?

"You foolish man." Dr. Smith's furious voice broke through Mathew's growing panic. "Do you realize what you've done? Dylan Brooks isn't just some ordinary man. He is the anonymous donor who has been keeping this hospital afloat. Without his donations, this hospital would struggle to keep its doors open, let alone maintain its top-tier facilities."

Mathew blinked in confusion, his mouth opening to respond, but the dean didn't give him a chance.

"He has been donating more than you can imagine, all while staying in the shadows. And you—you arrogant fool—just provoked him. If he pulls his funding because of this, the entire hospital will suffer."

Dr. Smith's voice turned colder this time. "I haven't taken action against you because of your past performance and experience. But now? Looking at your arrogance, I have to reconsider. Pray that Dylan doesn't uncover anything against you. If he does, you'll lose more than your job. Now get out of my sight."
