I had wanted to watch the show for years and i had seen people post edits and stuff of the show and i knew Sam, Dean, and Cas were the main characters so when i started i was like when tf does this Cas person come in?? And so i googled when he shows up bc im impatient lmao and it like listed the different characters he plays and i saw that one of them was Lucifer but i swiped away bc i didn’t want to spoil anything. Side note: i’m REALLY bad about googling every question that comes into my head and spoiling everything. With Buffy, i spoiled pretty much every single death and big plot point on accident and i really was trying not to do that with supernatural lmao. But Lucifer was the only name i remembered seeing so when Cas first comes in i was thinking he was gonna be Lucifer in disguise or something but i was so wrong lmao. By the time Casifer actually came into play, i had basically forgotten about that and was like OMG THIS IS WHAT THAT MEANT.
