Not a Chapter: But I Need Help

Okay so I've been a bit side tracked and need to decide on a certain plot for the next story. I've been trying to decide which one to write first but can't, so I need your help to decide which one. The plot with the most comments/votes will get published first and the one with the least, last. So the following are some story ideas that are ones I am having trouble with. Please help me decide!!!!
Yours truly,

Into the flames
-On a hunt Dean, Sam, and reader (sister or daughter?) are on a hunt that goes wrong. They are trying to save the family that is trapped inside a burning building that caught a flame when a flare gun goes off in the wrong direction. Sam and Dean both fun inside to save those inside forcing the reader to stay outside to care for the ones who made it out.

Ending:???

I am damaged
-The reader (sister or daughter?) is back from hell and gets in an argument with Dean. Dean is fed up with how she is acting and tries comparing himself to her. When she has had enough of his words, she explodes with rage and opens up about more than was expected.

Ending:???

In the high castle
- Honestly I'm not sure, if anyone has an idea for a title like this, tell me, I want to use this title but I have no clue on what sort of plot I should have.

Call them brothers
- The reader (sister or daughter?) gets possessed by (Lucifer? Gabriel? IDK) and Castiel is having a hard time adjusting to the situation. He and reader are dating but he isn't sure on how to continue his loathing hatred/complex sibling relationship and his love life with the reader.

Ending: depends on possession and the reader's relationship to Sam and Dean

I am a poet
- Short one shot but Sam and Dean found an old and weathered notebook in the map room and decide to read the contents. Turns out it is reader's (sister) poetry book.

Ending:???
