Chapter 4 – Final Chapter
After only a moment, they reappeared in a field, far from the motel room, where Meg instantly removed the arrow and was screaming hastily "Let's swap bodies! Now!". As soon as the arrow had left Castiel's body, he started feeling better and managed to ask Meg why. Meg answered screaming again "Because I can't heal you, but you can heal me! Come on, Castiel, we don't have much time!".
Castiel was now sure of what sometimes suspected, but didn't allow himself to believe: Meg had feelings for him.
This realization charged his batteries of inner power to the maximum. He could tell he was healing super fast. "Thank you, Meg, but it is not needed" he said. "I am healing. I will be alright".
It took him some moments to fully understand what Meg's feelings really meant. When he finally figured it out, he widened his eyes. "Meg is worrying about someone else than herself!" Castiel thought happily. It just now occurred to him that maybe, when a demon was hanging around with an angel, the demon could end up having some angelic qualities. "It is only normal" he said to himself and continued his train of thoughts "She can now feel how it is to like, to trust, to love someone. She doesn't know it yet, but she is a risen demon!". With a huge smile on his face, Castiel turned his head to look at her.
During all this time, that Castiel was making these thoughts, Meg hadn't said a word and was looking away, embarrassed that what she had been constantly refusing to herself, had now undoubtedly revealed. Now, Castiel was completely healed, yet he kept on lying on the ground, enjoying the starry sky and the caress of the cool grass.
Finally, Meg decided to break the silence. "What was that Crossbow?" she asked. "That was the Crossbow of Truth. It is ancient and very powerful. It was lost for many years" he answered. Meg stayed silent for a little while and then spoke again. "So, how are you, cloud hopper?" Meg asked trying to sound indifferent. "I am completely healed" Castiel replied. There was silence once more.
Meg, now calm, could solve her query and brought into her mind the last moments of their attack. How was Castiel wounded since Bobby was aiming at her? She smiled. She wasn't embarrassed anymore.
Castiel was the one who spoke first this time. "You know, I was thinking, there are four hours until the eclipse of the moon" he said. "And?" Meg asked. "And maybe, instead of just waiting, we could do something more... interesting" he continued with a naughty smile on his face. "I am again a virgin, while inside a female vessel" he concluded.
"Well, I know a way we can fix this... flaw" Meg answered and lay on top of him and kissed him.
The dawn found Meg lying on her back, hagging Castiel who was resting his head on her chest while playing with a tuft of his hair, both sweaty and exhausted.
The astronomical phenomenon had ended long ago without them having fulfilled their task. They had seen the lunar eclipse happening, but they ignored it. They were feeling relieved they hadn't freed Lucifer. So, they just kept on cuddling on the ground, finally carefree.
Castiel wasn't angry or lost anymore and Meg, for the first time in her long life, was calm. It seemed that their changes had brought them closer to each other, thus to humanity. They weren't evil nor moral anymore. They were somewhere in the middle, gray, like all humans are.
