It was set to stun. He set it to stun. He specifical told the guard with him that they were going after a vod and needed to set their guns to stun. Sure, the Chancellor had been very specific with his orders. ARC-5555 had attempted to assassinate the Supreme Chancellor and should be terminated on site, but this was a vod. This was Fives, Rex'ika's vod'ika. Rex loves his vod'ika, Fox couldn't harm him no matter what the Chancellor would do if he didn't follow through with the orders he was given. Rex loves his vod'ika and Fox loves his Rex'ika, he would never be able to do anything that would cause him pain. So why was there a smoking hole in in ARC-5555's chest? ~Or after Fox is forced to shoot Fives, one of his batchmates starts to realise something is terribly wrong with the Coruscant Guard
