It's well known that in the special forces, they train the soldiers to be able to work and react through the worst case scenerio. Sonya was already weakened from the energy strain she needed to fight off the creatures, but seeing Jane like this put her into high gear.
She put a hand to Jane's throat, muttering, actually feeling her energy drain even more as she coaxed the neck wounds to scab over to stop the flow of blood. When they stopped bleeding, she didn't stop, but changed coarse and was now actually pouring some of her energy into the young woman. It wasn't the same as a blood transfusion, which was what she was in need of, but it would get her out of the immediate danger zone and Sonya was able to stop when she saw that Jane's breathing wasn't so ragged.
Sonya felt herself become shaky, but she forced herself to remain focused as she torn off another long piece of skirt to wrap around Jane's neck as a precaution. "Come on Jane, you have to wake up. We have to get you out of here." She attempted to lift her up, supporting her neck. Never mind that Sonya was a practically a mess and that the only thing keeping her moving was adrenaline and urgency.
