The one where Dean is a firefighter and Cas is a writer; Dean rescues Cas from a building that collapsed, Cas cooks dinner for Dean as a ‘thank you’, and things progress from there.

“That was a good meal”
“Thanks. I was trying a new recipe”
“Are you that kind of writer?”
“What do you mean?”
“The kind that writes recipes”
“I think you call those writers ‘cooks’”
“I was trying to be funny. I saved your life, the least you can do is play along and laugh”
“Oh and here I thought my delicious home-cooked meal was enough”
“Wait, I just thought of a better way for you to thank me”
“Dean, I don’t do that on the first date”
“That’s not what I was thinking, but I’m glad to know that’s what you thought I was thinking.”
“Then what were you thinking?”
“That you write us a story”
“I think it’s better if we write it together”

…..

“You know, I never really understood why I do what I do”
“Risk your life putting out fires and saving people?”
“Yeah. I mean, I could be doing other things that are less exhausting—less life-threatening, but I chose this and I keep choosing this.”
“You get to help people, and that’s a good thing. Dean, you saved my life.”
“I know, but sometimes I wondered if this was really what I’m supposed to be doing.”
“And do you still wonder about this now?”
“I didn’t get it until I pulled you out of that building. One look at you and I just knew.”
“Knew what?”
“That I was meant for this. That it’s worth it.”
“I’m glad that building caved in on me then.”
“What were you doing there anyway?”
“Researching for a story I wanted to write”
“Well, was the it worth almost getting killed?”
“Yes. Otherwise, I wouldn’t have met you”

“We were having a moment. Why are you opening your laptop?”
“This is good stuff. I have to write it down”
