Five seconds

This was the time that Dario had needed to get rid of his taller, more muscular and heavier brother.

Clint now lay prone and moaning on the floor but in Dario's mind he hadn't suffered enough.

So Dario took aim and launched a powerful kick to his brother's ribs, breaking one of them.

The force with which Dario struck was such that Clint found himself looking at his room's ceiling.

The last thing he saw was his brother, towering over him, clenching his right hand into a fist and prepared to strike again.

Then darkness.

Dario struck with force and precision ... again ... again ... again, until his fist was covered with blood.

None of the two teenagers saw Jane crawl out of the room.
