She blinked away her tears and smiled back at him, rolling her eyes at how self assured he was, but was comforted by it. She thought about saying goodbye, but for some reason the words couldn't come out. If she were to say them, she'd feel like she was saying goodbye forever. So instead, she stepped into him again, leaning up to kiss his cheek. Her lips hovered near his ear and she whispered, "I'll miss you." before running off after the others. If she stayed any longer, it would only get harder - it was better to just do it fast, like peeling off a band aid.
But even when she was now behind the others, she couldn't help but look over her shoulder and give him one last glance before he left. Be safe...
