Once Emily and Kyle successfully escaped the school, the first thing Emily tried to do was blow up the school and all the soldiers in it. She had unconsciously moved her hands and was trying to make the place explode. This was something Emily usually did when a base of hers was compromised.
When Kyle saw this habitual move of Emily's he immediately held her hand.
"Emi!" Hearing her brother call her name, Emily finally realized what she was about to do. She quickly closed her laptop, and sighed. That was an extremely close call. Even if Lyner's safe room was extremely sturdy there was a chance that it might get broken if she blew up the entire school. She placed those bombs under the assumption that everyone would have evacuated.
"Thanks Onii-chan, my body just moved on its own. It's a good thing you were here with me. If I was alone, I might've done something irreversible." Emily sighed as she felt relieved while feeling a bit jittery.
