The Three Types

"Do you know what the term White Hat means?" 

Hearing an unfamiliar term and seeing Icarus smile, Bartosz starts to get extremely uncomfortable

He hesitates for a moment when he thinks of the way Icarus is likely to use this against him

Despite this hesitation, in the end, he lets out a sigh and as he shakes his head, he answers 

"Sigh! No! I don't know what that term means"

"Yeah, okay. It's quite understandable that you don't know what that means"

However, as soon as he sees this reaction Bartosz is not at all relieved.

In fact, it's exactly the opposite
