You were one of the hunters leaving the alternate world with Sam and Dean. You were told you'd driven to the exit portal in a bus. Oddly the bus was being driven by Lucifer. You were standing by some others and watched as the archangel stepped off the bus. He made eye contact with you. You were completely lost in the sight of his wings. They were black and some feathers wear a little damaged, but they were beautiful. You looked at a hunter who was handing you something and when you looked back over the archangel was gone.
A little while later you spotted Castiel and decided to ask him something that had been on your mind. "Castiel, why can't I see yours or Gabriel's wings?" you asked.
"Angels' wings are always invisible unless we show them," he explained.
"But I saw Lucifer's," you stated, "pretty sure he didn't show them to me on his own,". Castiel's eyes widened. "What?" you asked concerned.
"The only ones who can see an angel or archangel's wings without them being shown by them is their true soulmate,". He explained.
"Cas, are you saying I'm Lucifer's soulmate?" you asked.
"You saw his wings," Castiel explained, "so yes,".
Later you were helping load guns and other weapons Mary had tasked with doing when you heard a flap of wings. "Please, don't run off," Lucifer's voice said from behind you. You turned to face him. Again his beautiful onyx wings catching your eye.
"You know I can I see them don't you?" you asked. The archangel nodded. He knew the minute he looked over at you by the bus. That's why he fluttered off. He rarely felt emotions, but so many of them hit him at once when he saw you.
"I did, but I'll admit it did throw me off at first," he said, "I understand if you don't want to accept it and despite what others think or would say I won't force it,". His words were true. Despite who he was consent was everything to the angel. You walked over to him and looked into his ocean blue eyes.
"Do I repulse you Lucifer?" you asked.
"Of course not," he answered, "not at all,". You smiled as you gently cupped his face in your hands as you stood up on your tiptoes and softly pressed your lips to his. Lucifer was stunned at first but gently wrapped his cool arms around you along with his wings. At the moment everything was finally perfect for you both.
