Who Wrote The Pink Letter And Why (I Think I Finally Get It)

Today we talk about one of the mysteries in ASOIAF that has had fans debating for years. Just who wrote the pink letter and why? I think I finally found an answer that satisfies all of my questions and I am excited to share it with you. Let me know what you think, is this the reason the pink letter was sent to Jon Snow? How could this play out going into the winds of winter? I would love to hear your feedback.
