By season 11, Charlie isn't dead. She is a really good hunter and hunts with Sam and Dean and handles most of the FBI acts because she actually thinks its really fun. She's also been reading the Supernatural books every chance she gets. She's somewhere in season 8 when in the book Dean and Cas kiss. She goes to find Dean and says "I didn't know you and Cas kissed that one time" and Dean is like "wtf we didn't kiss". They go track down Chuck again to see what is happening. They get to Chucks house to see that he still lives there. Dean knocks on the door and when Chuck comes to the door he immediately tries to close it. Dean holds it open and yells "WHY DID ME AND CAS KISS IN YOUR BOOK?". Chuck lets them in and tells them he had thought about how monsters could read the books and know what moves they would use and use it to their advantage so he started changing up the fight scenes. Then he saw a destiel moment too good not to change a little and made it canon. Dean is kind of upset but learns to live with it and Charlie ships it forever and never dies
