Given a premise, an initial context, an original ending, and a counterfactual context, the task is to generate a new story ending aligned with the counterfactual context and as close to the original ending as possible. Each instance consists of a five-sentence story. The premise is the first sentence of a story, and the second sentence, which is the initial context, provides more information about the story's context and the story's general plot. The original ending is the last three sentences of the story. Also, a counterfactual context is a slight modification to the initial context. You should write a new story ending that edits the original story ending as little as possible to regain coherence with the counterfactual context. To sum up, you should write the last three sentences of a story based on the premise(first sentence) and the counterfactual context(second sentence) of the story.

Premise: Hailey was playing basketball in the gym with her friends. 
 Initial Context: Hailey fell down and rolled her ankle with all of her weight on it. 
 Original Ending: The ankle swelled up and turned colors because of a very dark bruise. Hailey needed to go to the doctors and a appointment was made for her. The doctor saw her and said her ligament was torn and needed surgery. 
 Counterfactual Context: Hailey fell down and hurt her arm with all of her weight on it.
The arm swelled up and turned colors because of a very dark bruise. Hailey needed to go to the doctors and a appointment was made for her. The doctor saw her and said her ligament was torn and needed surgery.
