The Things Get Out Of Hand

...

Seeing that even in this situation, Icarus is still in the mood to make jokes. Wrenn is slightly shocked and thinks

'Well, I can't deny that this brat has a frightening mental stability. I think he can handle even more pressure than his father or Bartosz. Something quite surprising given his age'

Once it gets to that point, Wrenn's eyes start to cool.

'Still... I need to make him understand who's in charge here!'

Believing that Icarus still doesn't understand how serious he is, Wrenn decides to give a little demonstration of what he's capable of

He then points the gun at Icarus' shoulder and without any hesitation pulls the trigger

BANG!
