Ok, so I was thinking and I realized, they killed Adam...which means they aren't afraid to kill minor characters we love (even if he was on screen for all of two minutes) so now I'm scared for all the minor/minor major characters like Colleen, Sam,  Matt, Shay, Veronica, or even Krolia. Adam was obviously really important to Shiro (seeing as we have been told they were close to or maybe even engaged when they broke it off) so now (at least to me) no one is safe...
