Cait had kept her eyes down as she pulled away, not wanting to risk eye contact for many reasons - the emotion welling up inside her (and possibly Fred as well) and the illusions. She felt regret at letting Fred see her so open was building inside her. Fred was the only person she felt she had to be open with.
She tensed for a split second as Fred's lips pressed against hers. But Cait kissed the other girl back as long as she was allowed. And as Fred stood and ran away, she brought her hands up to her face as the tears rained down.
