Alex nodded. He wouldn't hesitate, now, to blast anything that came too close and posed a threat. He stood firm, his legs slightly apart, his stance saying don't mess with me. Not that a Stormtrooper would really care one way or the other about his stance and body language.
The only language they seemed to know was violence. Well, there was one less to worry about after Alex took it down with the blaster he'd stolen from a fallen comrade. The rush of adrenaline he felt when the enemy went down was some kind of high, for sure. But he tempered it down, because it was a dangerous high.
He wasn't a killer. He did't like the thought that he was. But he had vanquished an enemy and kept someone else safe. Two someones, really. He didn't know Raven's name and didn't even know if he'd ever see her again, but for today at least, they were partners of a sort. Alex felt like he'd earned his stripes, and it felt good despite the fact he'd killed someone. Or something.
