Hi, sorry for barging in. I was the guy that got the blue message, Brill.
The Xeno that shot at you is a terrorist with a strong dislike towards Junkers. My character is a quasi-lawful mercenary registered on a bounty board, who gets paid for killing junkers by your Kusarian arch-enemy, the Hogosha.
So you see, there was no way we weren't going to attack you. Our only objective was to destroy your ship, so I can get paid and the terrorist could create some terror, that was the very reason we were in Texas. None of us were pirates. Moreover, other Junkers were venturing out of Puerto Rico as we were talking, and the organized Junkers are really difficult to get at - you have to hit them hard and fast, so we didn't want to get too delayed and miss our window of opportunity.
We both also gave you ample time to reply, and talked with you for a little while before blowing you up. That was more of a "last words" sort of thing than it was a chance for you to talk your way out of us attacking. The "3, 2, 1" was a countdown for your captain character to get to his escape pod as a clear indication that you were going to get shot at, rather than 3 seconds for you to reply - you had plenty of time to reply before that, and you did.
Had we been on pirate characters, you'd been able to pay and negotiate with us - it just happens that you came across two characters with a particular lust for Junker blood, and our sole criterion for success was the destruction of your ship.
