The rest of the team left, leaving Spencer to his thoughts.
He thought about all the events that had happened over the last few hours and how it had been Castiel, the beautiful angel who was making him feel this way.
That was when Spencer heard the faint flutter of wings and a "Hello, Spencer." This was so unexpected, Spencer jumped out of his skin and turned to face Castiel.
"Castiel..." Spencer's voice broke off, not knowing what to say. The angel took a step towards the human, who intrigued him, he was incredibly smart and handsome with his high cheek-bones and dark brown eyes that he could somehow, lose himself in.
"Spencer," he started, "I'm sorry that I threaten what you believe. I came to see how you were doing."
"I-I'm fine," Spencer was so struck by the beauty and kindness.
"Good, I'm glad." The angel walked around the room, studying Spencer's stuff silently. "You have been under my observation for half a year, the angels are making sure you will keep ridding the Earth of your 'unsubs', it's part of a greater plan,"
Spencer, unsure of what to say, stayed silent.
"But, my superiors think I've gotten a little too attached to watching you," Castiel said, turning to look at Spencer in the eye, "and they're right to think so. Spencer, as I've watched you, I've come to know you. I've become intrigued by you and I do not understand these feelings fully, but I like being around you..." He trailed off, and looked down, almost shamefully.
"Castiel..." Spencer said again, he closed the gap between them and held Castiel in a soft embrace, which the angel awkward returned.
Castiel pulled away, whispering, "Spencer, I cannot, it's against my orders,"
"Castiel, Cas, I don't care what your orders are, I just want to be with you," Castiel suddenly didn't care either, he took hold of Spencer's neck, pulling him into a clumsy kiss. As their lips met, Castiel felt tingles of joy run throughout his body and finally an understanding of his feelings. Spencer pushed his hand around Cas' body, his other hand winding into the angel's scruffy hair, deepening the kiss.
Castiel pulled away again, leaving Spencer breathless, he murmured, "You, Spencer Reid, are truly one of God's wonders." And although, he wanted to kiss him again, he pulled himself gently free, knowing he'd have to leave.
Spencer saw that thought of having to leave flash through his angel's eye, "Don't leave me," he said quietly.
"I'll be back in the morning," Cas whispered back, "You've been through a lot and need the time to adjust."
Spencer nodded and Cas placed a softer, more innocent kiss on Spencer's lips and left. His wings, although not visible to the human eye, made a slight breeze on Spencer's face, making the human smile.
He had an angel, impossible, but an angel none the less.
