Looking for a spread about a broken friendship.

My close friend (B) is looking to have her cards read. She recently had a bad experience with her best friend (F). F treated B really disrespectfully and had overall been super manipulative and controlling throughout the friendship, wouldn’t let her be friends w anyone else, etc. Honestly we are thinking F may be a sociopath. I read F’s cards a few months ago (general past present future) and she said it didn’t resonate at all. I just thought I had an inaccurate reading, but looking back after what happened she had pulled the devil rx and knight of cups rx (don’t remember the other) which actually make a lot of sense now.

Can anyone recommend a spread I can do for my friend B to give her some insight on F? Intentions, subconscious, conscious, etc. Thank you!
