As far as JE is concerned, those characters were all in the area, so they responded as best as they could, the fight would have gone better, until they went into rescue mode, Paragon held up the roof, Redline moved to save people and Atlas got jacked, I wouldn't say there is a secret agenda, but in the end saving people made out better then jacking Pantheon.
Paragon and his buddies may have underestimated the capabilities of Pantheon in a stand up fight, and they didn't know Rei was on their side. They have no intel on him, it may have not been the right decision to strike at them in the club, but well stuff happens
