Input: Consider Input: Passage: Hotshot ensign Alan Drake, fresh from the flying academy at Pensacola, Florida, gets off to a bad start with the pilots of an elite squadron, nicknamed the "Hellcats", to which he has been posted in San Diego. Making a nearly disastrous landing attempt in heavy fog against orders and disqualifying the squadron during a competitive shooting exercise by colliding with the target drogue does not endear him to his fellow pilots. He also asks out a woman he has met, Lorna, not knowing that she is the squadron commander Billy Gary's (Walter Pidgeon) wife.
However, Drake is earnest and contrite. He mixes with the Hellcats at the Garys' large house, which the sociable couple have opened as an unofficial officers' club. His flying and his social errors are forgiven, and his fellow pilots accept him, nicknaming him "Pensacola".
Drake further proves himself when he helps Lieutenant Jerry Banning solve a problem in a blind-landing apparatus he is developing. Just after Commander Gary is sent out of town on assignment, Banning decides the apparatus is ready to test in fog but it fails and Banning is killed. Working with Banning's assistant, Drake soon identifies the problem, but no further testing is allowed until Commander Gary's return.
Banning had been a childhood friend of Lorna Gary, and is not her first friend to die. She sinks into a deep depression. She also knows that Gary will expect her to hide her feelings and carry on, something that is very much not in her nature. Drake, appreciating the help the Garys gave him when he arrived, visits her at her home, and convinces her she should not suffer alone. They go for walks, drives, and tennis; he amuses her with jokes. Finally, at a restaurant she reaches for his hand and in doing so realizes she is falling for him. She quickly breaks away, and says she cannot see him any more.
Question: What is the last name of the person that Lorna realizes that she can't see anymore?

Output: Drake.

Input: Consider Input: Passage: Following the release of The Final Cut, Waters embarked on a solo career. In 1984, he released his first solo album, The Pros and Cons of Hitch Hiking, a project about a man's dreams across one night that dealt with Waters' feelings about monogamy and family life versus "the call of the wild". In the end the character, Reg, chooses love and matrimony over promiscuity. The album featured guitarist Eric Clapton, jazz saxophonist David Sanborn, and artwork by Gerald Scarfe. Kurt Loder described The Pros And Cons of Hitch Hiking as a "strangely static, faintly hideous record". Rolling Stone rated the album a "rock bottom one star". Years later, Mike DeGagne of AllMusic praised the album for its "ingenious symbolism" and "brilliant use of stream of consciousness within a subconscious realm", rating it four out of five stars.Waters began touring in support of the album, aided by Clapton, a new band, new material, and a selection of Pink Floyd favourites. Waters debuted his tour in Stockholm on 16 June 1984. The tour suffered from poor ticket sales and some performances at larger venues were cancelled; Waters estimated that he lost 400,000 on the tour. In March 1985, Waters went to North America to play smaller venues with the Pros and Cons Plus Some Old Pink Floyd StuffNorth America Tour 1985. The Pros and Cons of Hitch Hiking has been certified Gold by the RIAA.In 1986, Waters contributed songs and a score to the soundtrack of the animated movie When the Wind Blows, based on the Raymond Briggs book of the same name.

In 1987, Waters released Radio K.A.O.S., a concept album based on a mute man named Billy from an impoverished Welsh mining town who has the ability to physically tune into radio waves in his head.

Waters followed the release with a supporting tour also in 1987.
Question: What is the first name of the character who simulates a nuclear attack?
Output: Billy.
