Sonja, still more than a little surprised that her scheme for Sarin had paid off, saw Shank and Bouncer go down and grinned in satisfaction. "That's the ball game!" she had said excitedly, before the sound of the explosion had reverberated in the enclosed space. She reflexively threw herself down behind the teller's counter, for what scant protection it would provide, before taking a cautious peep over to take in the situation.

She grimaced at what she saw. She had foolishly assumed that Boomer and Burnout were both down for the count, yet here they were, hurling blasts and fireballs at the other heroes. The henchmen, armed with various automatic weapons, seemed to have rallied around their superpowered backup and were continuing to pour it on. Volt was drawing most of their ire, and it was clear to her the young man had deliberately drawn their attention. The lanky Scot was brave, he was smart, and now that she saw him out of costume he was also kinda cute. No way in hell was she going to leave him high and dry. 

The Spirit of St. Louis assessed the two foes, hastily threw together a plan. It would be a strain on her magical ability, but if it worked it would buy them enough time to regroup. She took a deep breath, ducked back behind the counter, hopefully unnoticed.

A flick of the wrist, and a fireball of her own rested in her palm. Hopefully it wouldn't singe her cuff, but she could worry about that later. She lifted herself out of cover just long enough to ascertain that Boomer's back was turned, then heaved the fist-sized fireball directly at the small of his back. If it hurt him, great, but it was more important just that it was noticed. Sonja immediately ducked back behind the counter, her heart racing, then concentrated as hard as she could. Mentalism, when done on stage in her old profession, relied on intuition, memory, and body language in order to influence the way an audience thought. Sonja, however, with her abilities, could do the next best thing: place thoughts directly into the head.

Boomer wasn't very bright, she remembered Olympia saying. And now that he had received a fireball to the back when he wasn't looking, there was a nagging voice in his head that was certain Burnout had done that on purpose.
