Castiel had just finished cleansing his angel blade of mixed bloods when he felt the presence of another angel, which was startling to him. Fearing the worst, the worst being an angel assassin, he was relieved to know it was an old friend of his. The fear on his face quickly wiped away and instead turned into a welcoming grin. Castiel hadn't seen Rose in ages and feared that with the intense wars going on in Heaven, she had died fighting. She was here, in the flesh, though, and he felt content knowing the intruder had not been sent to kill him.
"Hello, Rose," Castiel greeted, but quickly realized that angels do not pop in to socialize as the humans he had grown accustomed to had. His smile turned flat as he knew something must be wrong for her to be here. "How did you find me?" He asked
"Castiel, I heard your prayers. I heard your worries about your human friends and your worries on the outcome of the civil wars going on in Heaven. I came to you to talk to you about it and possibly release some of the anxiety that has built because of it. I am here now, what is your main concern?" Rose kindly stated, giving her reason for sudden appearance.
"How do I choose, Rose? Between Heaven and humanity? I am a part of Heaven, so I feel I must be loyal, but I have grown so close to humanity and all it has to offer." Castiel confessed. It was truly the biggest conflict he had yet been through, and he didn't know how to handle it, hence praying to other angels to help him.
"Sometimes, Castiel, it chooses you. Not the other way around." Rose paused, careful about how she would choose her next words. She didn't want to stress him out more than he already was, so she took a deep breath and continued with carefully chosen words.
"But you and Dean, you chose each other. You two have more special of a bond than even the greatest bond among angels to angels, or even angels to God, and thats saying something. I know how you feel about Dean and I know you two are chosen for each other, so if I were you, I'd chose the stronger bond." Rose took a deep breath and looked over to Castiel to see how his reaction on her decision for the answer of his question had panned out.
Castiel's eyes widened and he quickly glanced down at his shoes so that Rose could not see the pure confusion in his choice. He did not know whether or not to choose humanity, as he had his friends and what he considered family and Dean. Dean. She had said the two chose each other, and that kind of bond must surely trump the bond he has with fellow soldier angels. Castiel did not know what kind of bond she had meant, though. Was she referring to the fact that their bond of friendship was so strong it was almost familial? Or did she mean that they chose each other and had a strong bond in a romantic way? His heart fluttered at the thought and he had to calm the butterflies in his stomach. Castiel almost hadn't noticed the flapping of wings as Rose vanished.
Castiel had started to think about this more and more, countless memories of gazing upon Dean's perfect complexion, or his jade eyes, or even the way his smile fit his face. Castiel sighed and closed his eyes when he connected the thoughts. Rose was talking about a romantic bond. Surely, Dean would not have feelings for him back, right? Castiel knew that Dean always had a romantic interest in women and never for men, let alone celestial beings. He bit his lip and sighed once again, hoping that in whatever possible way, Dean might have even a quarter of the feelings for Castiel that Castiel had for Dean. It was probably impossible, Castiel told himself countless times. He collapsed to his knees and realized he couldnt say anything about this to Dean, otherwise their friendship might be ruined forever.
Castiel turned on his cell and attempted to call Dean. It rang for what seemed like hours until he finally picked up.
"Hey Cas. What's up? Anything wrong?" Dean asked, his tone worrisome.
"Oh, um, it's nothing. I'm done with the latest order I had, so I wanted to check in with you guys. I'll fly there, but where are you located?" Cas questioned with a happy tone. He would finally get to see his favorite brothers. After obtaining information over the phone, Cas quickly flew to the location Dean was, and it appeared to be yet another run down hotel. He could sense Sam's presence inside room 118, so he walked up to the door and knocked. Sam answered the door with an overwhelmed look on his face. Cas immediately knew something was wrong.
"Cas… Dean, he… he just disappeared. I- I was talking to him and I turn around for one second and he's gone. I was about to call you to see if you would come… but I guess here you are." Sam was skittish over every move Cas made, almost as if he was afraid that he would be snatched up too. They both tried calling each of Dean's cells multiple times, but they would ring and ring and ring until they hit voicemail. Sam noticed that Cas seemed on edge.
