Stopping immediately at the girl's sudden action accross her throat, Gavin tilted his head to the side and wondered just what the girl was trying to do. Something about someone being slashed by the throat? Killing? Where he came from a hand signal accross the throat like that came right before they pointed to their target, an order to kill in the heat of a battle. But, it really didn't seem dangerous in the cells at that moment, so Gavin was beyond confused. Maybe to shut up or wind up dead? He had absolutely no idea at this point, but rather be dead than rot, right? Though Luther was coming, so it's not like he'd rot anyways. The blond sighed, he didn't have a problem with not talking, but not talking wouldn't get him anywhere.
Thankfully, this girl's foot just kept moving, so Gavin didn't have to. He observed and was able to focus directly on her, even if not with his eyes. Words however didn't come to him, even if he did want to say something. What was to be said? Anything vital had been. It wasn't like asking how the weather was was going to be much of a surprise. Frustration was hitting him like a sledgehammer, and it was prying at him to use more of his magic. It was always easier to vent like that, it made it so that Gavin could be the calm, stoic guy that he was without too much of a problem. While it was extrmeley straining to set up a barrier around the girl, it wasn't impossible. It was one of those things he was taught but was never adept to, sort of like healing and the whole spectrum of magics. Water, earth, recovery, dark magic, they were all useable just very limited to the point of frustrating and that after using them one would want to sleep. Lightning and wind were what made the blond feel empowered, they felt limitless.
Slamming his hands around the bars of his cell, Gavin smirked. Voltage was spreading everywhere freely, probably reaching more than just the floor they were on too, though completely avoiding the girl that Gavin had put a little bubble around, translucent in color and water in nature, making the electricity more attracted to it than to the girl that was envelopped by the bubble. The hard part would now be that when he stopped and the barrier was no longer needed to not splash her in the face. From his experience, woman didn't particularly enjoy that, and the last thing Gavin needed was a very angry woman on his hands when he had nowhere to escape to.
Gavin took his time however, now trying to follow his lightning more than anything else, around the building, trying to find out where he was with his senses. Might as well utilize needing an energy drain. It wasn't like the image was that fantastic, but it was better than nothing. It showed him enough that Luther would have an easier time finding it at least.
'I'm below ground somewhere. I think the building is pretty large itself. I can't tell that high up, but there's more than two floors, lots of security. Oh cra-'
Immediately stopping his fit of lightning, Gavin completely forgot about the barrier he had up with his attention diverted and all water instantly smacked the girl at full velocity. Only when he heard the sploosh did Gavin turn to face the girl and instantly get fright in his eyes. He had just dunked a woman in water after he had burned her. What a great way to start a friendship. Not to mention, the pounding of footsteps that were coming in his general direction now.
