Grunan notices Alka and co, its a long way away... "No..." Grunan tries to use his Radio... He then realizes, he can force Al to switch sides again. "me and... Al... I think we failed... Our betrayal was a mistake... but we were in it together... We needed that weapon... WE NEEDED IT... we thought we could take it from you... From Nucleon... from everyone..." Grunan growls... "And that's what we intend to do."
Grunan grins. Misinformation, distraction, and of course, an end to Al's betrayal. Even if he kills Drago, Xander, Geoff... he would never return to the enemy. They probably knew anyway, after all, he was a traitor, if Grunan was a traitor, his friend probably is already known as a traitor... in a strange way he might have just saved his life.
