Why This Must Be Read: Budapest. In the harshest of ways full of all those unsaid but completely felt things. A very mature and highly likely canonical possibility of how their relationship functions between partner and friend and how it could shift into more. Quite fluid and wonderfully abound with inner struggle manifesting itself in action and dialogue. It's like a punch to the face and then your assailant finds the nicest piece of meat to keep the swelling down.
