Val had been silent during the introductions, as well as when the Professor was introducing the training center. When the giant robot attacked, she was also silent but for an entirely different reason. She watched as Alex and Danny went off, with Ali cloaking them but she couldn't cloak the heat signatures as well, Valentina didn't know what good that would do them. She observed Casper as he tried to come up with a plan, and then he mentioned he couldn't replicate something over two pounds. 

"Casper, is it possible you could duplicate me in my electric form?" She asked him, curiously. She, in her simplest form, was a lot of energy. Striking something at full energy does a lot of damage, which is why St. Petersburg had a blackout when she first discovered her powers. Since then she's learned how to travel in bits and pieces as to not damage the vessels she uses to travel in but perhaps if he could replicate her even once, she could do some damage with Kimberly's help. 

If not though, Val glanced at the door. She didn't know enough about it to know if it would open or if it would deadbolt if she fried it, and she wasn't keen to try in case the latter happened. She could possibly break the observation glass, with Kimberly's help but both that and her first plan requires Kimberly to be able to catch her before she goes into a conduit. Once she's in a conduit, without restricting herself, she would fry the system and that wouldn't be in their best interest at all. 

"Kimberly, how fast are you at harnessing electricity?" She asked as she kept her eyes up on the robot, who hadn't done anything for a suspiciously long amount of time and that was starting to worry her. Robots don't usually stop attacking unless they're sentient, or someone who's controlling them is sentient, and has a plan. Their plan would probably be a lot more coherent than their plan at the moment.
