A ship of the line was a type of naval warship constructed from the 17th through the mid-19th century to take part in the naval tactic known as the line of battle, in which two columns of opposing warships would manoeuvre to bring the greatest weight of broadside guns to bear. Since these engagements were almost invariably won by the heaviest ships carrying the most powerful guns, the natural progression was to build sailing vessels that were the largest and most powerful of their time.

From the end of the 1840s, the introduction of steam power brought less dependence on the wind in battle and led to the construction of screw-driven but wooden-hulled ships of the line; a number of pure sail-driven ships were converted to this propulsion mechanism. However, the introduction of the ironclad frigate in about 1859 led swiftly to the decline of the steam-assisted ships of the line, though the ironclad warship became the ancestor of the 20th-century battleship, whose very designation is itself a contraction of the phrase "line-of-battle ship."

Peter decides that he must follow the painting and the ticket to Montreal, and Caitlin insists on going with him because she is with Peter in the painting and she also wants revenge for her brother Ricky's death.

Claire tries out for the cheerleading team, where she is off-handedly dismissed by Debbie, despite being the best candidate. West convinces Claire to humiliate Debbie so that she can use cheerleading as a cover for their relationship.

Debbie is drinking with the other cheerleaders as Claire comes and asks to speak with her in private. After Debbie's second refusal to let Claire join the squad, West appears in a ski mask and picks up Claire, dropping her and ostensibly killing her. Debbie runs as West gives chase.

The police come to Costa Verde High School, where a frantic Debbie tells them that a masked flying man chased her and killed Claire. Claire appears, having regenerated, and tells them that she doesn't know what Debbie is talking about. The police find Debbie's alcohol and arrest her. Claire and West sneak away to talk, and another cheerleader tells Claire that she is now in the squad since Debbie has been suspended from school for drinking on campus.

Sidney K. "Sid" Meier (born February 24, 1954) is a Canadian-American programmer and designer of several popular strategy video games and simulation video games, most notably Civilization. Meier co-founded MicroProse in 1982 and is a Director of Creative Development for computer game developer Firaxis Games, which he co-founded with Jeff Briggs and Brian Reynolds in 1996. He has won several prestigious accolades for his contributions to the computer games industry.

Sid Meier was born in Sarnia, Ontario, Canada. He graduated from the University of Michigan.

Meier founded MicroProse together with Bill Stealey in 1982. MicroProse initially developed flight simulator video games, such as Silent Service and F-19 Stealth Fighter. In 1987, the company released Sid Meier's Pirates!, which also began a trend of placing Meier's name in the titles of his games. Meier later explained that the inclusion of his name was because of the dramatic departure in the design of Pirates! compared to the company's earlier games. Stealey decided that it would improve the company's branding, believing that it would make those who purchased the flight simulators more likely to play Pirates!. After the release of F-19 Stealth Fighter, Meier decided to focus on developing strategy games. He later said, "Everything I thought was cool about a flight simulator had gone into that game." Inspired by SimCity and Empire!, Meier created Railroad Tycoon and later the game series for which he is most widely recognized, Civilization, although he designed only the first installment. Meier eventually left MicroProse and in 1996 founded Firaxis Games along with veteran designer and gaming executive Jeff Briggs. Today Firaxis makes strategy games, many of which are follow-ups to Meier titles, such as Civilization V and Pirates!. In 1996 he was awarded US Patent 5,496,962 for a "System for Real-Time Music Composition and Synthesis" used in a product called "CPU Bach".
