Q: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Passage: Celia Crowson and her family go on holiday to the south coast of England in the summer of 1939. Soon afterwards the Second World War breaks out and Celia's father joins what was to become the Home Guard and her more confident sister Phyllis joins the Auxiliary Territorial Service. 
Fearing her father's disapproval if she moves away from home, Celia hesitates about joining up but eventually her call-up papers arrive. Hoping to join the WAAF or one of the other services, Celia instead gets posted to a factory making aircraft components, where she meets her co-workers, including her Welsh room-mate Gwen Price and the vain upper middle class Jennifer Knowles. Knowles dislikes the work they have to do at the factory, causing friction with their supervisor Charlie Forbes which eventually blossoms into a verbally combative romance.
A nearby RAF bomber station sends some of its men to a staff dance at the factory, during which Celia meets and falls in love with an equally shy young Scottish flight sergeant Fred Blake. Their relationship encounters a crisis when Fred refuses to tell Celia when he is sent out on his first mission, but soon afterwards they meet and make up, with Fred asking Celia to marry him. After the wedding they spend their honeymoon at the same south coast resort as the Crowsons went to in 1939, finding it much changed with minefields and barbed wire defending against the expected German invasion.
A:
What are the first names of the couple who meet and make up?
