Given the task definition, example input & output, solve the new input case.
Given a premise, an initial context, an original ending, and a new ending, the task is to generate the counterfactual context that is aligned with the new ending. 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. The original ending is the last three sentences of the story. Also, you are given a new ending that can provide the new story with the same premise. You should write a counterfactual context to explain the small differences between the original and new endings. More specifically, a story context contains the general plot of the story. And a counterfactual context is a slight modification to the initial context. To sum up, you should write the second sentence of a story based on the premise(first sentence) and the new ending(last three sentences) of the story.
Example: Premise: Brad stole the ball from the opponent. 
 Initial Context: While he was running with the ball, he noticed his friend. 
 Original Ending: He threw the ball in the air, near the hoop. His friend grabbed the ball and made a drunk. That score put his team in the lead. 
 New ending: He stopped dancing and threw the ball in the air, near the hoop. His friend grabbed the ball and made a drunk. That score put his team in the lead.
Output: While he was dancing with the ball, he noticed his friend.
The answer is well in context with new ending and it is counterfactual to initial context.

New input case for you: Premise: Katy went to Red Lobster for the first time. 
 Initial Context: She was so excited to try out a new restaurant. 
 Original Ending: Katy had never eaten lobster before so she tried it that day. She finished her meal and then she began to itch all over her body. It was that day Katy discovered she was allergic to lobster. 
 New ending: Katy was just meeting friends, so she didn't try to eat anything that day. They finished her meal and then one of Katy's friends began to itch all over her body. It was that day Katy discovered she wasn't the only one allergic to lobster. 
Output:
She was allergic too all types of sea food.
