Kaleeth, from her position under the water, could see what was happening. She saw that Sabine had been grabbed by one of the bandits, she saw them backing towards the camp, and she saw Leaps crest the hill. There was little question about what was about to happen, and there was no way she would be able to just do nothing. She wondered if she should transform, or if she would even have time. The bandits did not know she was there, so even in this form, she could still do something. 

Looking down, Kaleeth rubbed Newt's head once more. "I need you to listen to me, little one. Stay right here under the water, and don't go anywhere, or make any noise. Okay? Don't do anything until mommy comes back to get you."

Obviously, Leaps did not have the capacity to fully understand the situation, so his actions were based on instinct. He saw that Sabine was in danger, so he acted immediately. Lightning pulsed through his body, which he quickly shot out at the bandit holding Sabine. The electricity coursed through his body, and into Sabine as well, to a lesser extent. It was not lethal to either of them, but rather importantly, it did cause the bandit to drop his dagger without cutting her throat. If she was able to overcome the effects of the shock, she could fight back against him. If not, Leaps was presently in the middle of pouncing at her attacker. 

As the attack had been sudden, and from an unexpected direction, the Bosmer crossbowman glanced off to his right towards Leaps, which delayed his shot. Immediately as Leaps shocked the bandit, Kaleeth emerged sprinting out of the water, screaming at the top of her lungs to grab the attention of the crossbowman she was charging towards. She just wanted to keep him from shooting any of her family, regardless of the danger to herself. Her hope was that she could reach the Bosmer before he could swing his crossbow around. 

Pieter was afraid, more than he ever thought he had been, so there was not much rational thought going into his reactions. He had a soldier's training and knew he should help, even though he had no exact plan for how to do that. As soon as the bandit was shocked and their enemy distracted, Pieter ran forward to try and help Sabine. His lack of anything to actually fight with was not a detail that registered too strongly in his mind. 

While the bandit holding Sabine had been briefly incapacitated, his allies' reactions were varied. The leader, being the most disciplined, brought her weapon to bear against the most present threat. Leaps was charging towards them, and she intended on meeting him with her blade. The crossbowman was trying to level his weapon at Kaleeth, while the other archer had an arrow drawn, but seemed to be caught briefly trying to decide what to shoot. The last bandit, another Imperial with a shortblade and a buckler, looked like he was going to try to cut down Sabine.
