Alma Coin prepared to reveal herself. Snow was giving some speech about the rebellion, but for once, she wasn't paying attention. She was wondering if he'd recognise her (there was a small chance). If he remembered her name (he must). If he'd covered up her games, repeated the 38th Hunger Games as if 23 children hadn't already died that year (he would've, knowing him).
Someone in the room started a countdown, and President Coin cut her wondering short to address the man who had made her a killer. She hoped he was shocked.
President Snow knew when he asked to have a speech written for a broadcasted address that he wouldn't get to deliver the whole thing. The rebels were breaking in quite frequently now, and they'd be sure to throw in a video of their own when they found out what he was telling the country.
What he didn't expect was the face staring back at him when the rebels came through. Snow had assumed she'd died decades ago when she had escaped the Capitol after winning the games. Though she had aged,her face was still so similar to the sixteen year old who had been pulled out of the arena all those years ago that he didn't need to hear her introduce herself to know that Alma Coin was back and ready to defy him once more (though, he supposed, she'd already been doing that for years, hiding out in the abandoned district and plotting to overthrow his government for enough years that he'd almost forgotten that before there were true Career tributes, there were defiant ones).
Still, he was surprised to learn she'd survived long enough to make her way to District Thirteen. President Snow leaned back in his chair. Her return explained everything, and he knew what to do now that he knew who he needed to out-scheme.
