[@Lunar Templar]As the rifle exploded Alex asked: "Wait?  That was insulting? I didn't mean for it to be.  I was just using the explosion to cover this."

Through the explosion from the Lupis Rifle, the Freedom jabs forward with the beam saber it had out, which is countered by one of Zero's beam sabers.  Alex then pulls out his second beam saber with his free right hand and slashes forwards.

(The tone in Alex showed he didn't want to show any insult to his opponent.)
