Right, you seem to be failing to understand what I'm saying. Perhaps I should be a bit more clear.
In this case, Yes, Nasir was the first person to make physical contact. The botanist, however, started the problem by tripping him in the hallway. After Nasir shoved the botanist, he got up and instantly started swinging, so Nasir backpedalled which swinging back. When you took out your flash, Nasir ran away but slipped on a peel and started getting punched. He got up and took two steps back, and swung again, and that's where you flashed him. The only time Nasir 'chased' the botanist is when he was brought into the hallway near the end of the fight.
In the holodeck thing Nasir was /not/ 100% the insigsator, the fact that security followed them from the hallway, and kept harassing Nasir, Shayla, and Krisha, while trying to find any excuse to bully them and arrest them makes you the instigator. And Nasir was related in this event because he was involved with it the entire time. He only got physical, after security did and then the brawl happened.
And your Chief engineer was being a pain in the ass to Nasir, so yes he was being slient. Yes, Nasir was uncaring about your threats to fire him because he's completely aware as to who the captain was that round and knew that they would see how full of shit your CE was. So he was unafraid.
And no, I have no need to metagrudge against you. Nasir doesn't like your CE, how he does things, or how he talks. Its as simple as that.
