Annette glanced about nervously as Misaka seemed to get more enraged, if the red tinting her cheeks was any indication. Kuroko on the other hand seemed completely oblivious, supporting the notion she had voiced, but that wasn't necessarily indicative of anything. Given how the others seemed to be bracing themselves, she just wondered if she had to be worried about being blasted. 

then the deluge, and Annette turned away, wincing at the bright blue light as all that built up electricity was released directly into Kuroko. Honestly it left her worried for her own safety, but given the lack of being shocked she had to assume that she was fine. Kuroko on the other hand....

The fading light gave evidence to that with the sound of a thud as the fried teleporter hit the ground, twitching but still conscious and alive. She probably wouldn't be doing anything, like talking, soon though. Well then, that had been impressive, and an example to keep in mind that she should not earn the Electromasters ire. 

Annette chuckled nervously as she surveyed the scene. "Um, Misaka, wasn't that a bit of an overreaction," she asked hesitantly. It seemed like it to her, but she would admit that she didn't have the history those two had.
