Galen's hand holding his saber trembled slightly, his mind and emotions in chaos. He could almost hear Vader's booming voice telling him to embrace the Dark side or be destroyed. But it was countered by other voices and images ranging from Kota to Shaak Ti to Mara telling him to abandon his hold on the Dark side. By some small miracle of the Force, his thumb was staying off of the button.
Hearing Mara's question, he shut his eyes, though that was a mistake. He could see that blonde man's smug face and Gaia's lifeless body. A tear slipped past his guard, the feeling of sorrow and loss slipping through the cracks in his wall of emotions.
Letting his eyes open, he stared at Mara. "If you won't move willingly then I'll make you," he said, his voice struggling to hide his emotional pain. He stopped resisting, his thumb moving down and landing on the button. The snap!hiss of the lightsaber echoed on the quiet side street and he stared at Mara, the blue blade shifting into a ready position.
He studied her for a few more moments, as if giving her a last chance to move before he leapt forward and swung his blade at her, his eyes growing focused with the thought of battle.
