The Sentinels tell me we'll be okay

Sarah needed not to be told twice - from the moment Charon had jumped out of the pond with the frog between his jaws, her eyes had been fixed on the creature. And, when it was let go, she pounced at it imediately. Yet she had not taken in account the fact that the amphibian was still very much alive and was dead set of staying that way too. It made a fantastic leap out of the girl's grasp and then away towards the forest.  The girl went after it, not wanting to give Terance a chance to better her.
