Prologue/Michael finds out his brother's secret

After kicking H.I.V.E butt Team Arrow returns to their headquarters wiped out from the battle, unknown to them Michael is following them close behind but being really quiet like a ninja. He searches the wall for the button that he saw Oliver (Green Arrow) press and he finds it and it opens the doors to the lift and he got into it and he walks into the Cave and is nailed by the butt of Spartan (John Diggle's) Nine Mill.

Ow my head what the hell was that whoa Michael says as he sees three arrows and two nine mill hand guns pointing at him.

Green Arrow (Oliver) looks at him.

Who are you what are you doing here and how did you fine the button Green Arrow (Oliver) says as he looks at Michael.

Then Typhuss (Red Arrow) recognized him.
