The second time that Viktor Navorski meets Amelia Warren, he lends her his handkerchief. When she returns it, she asks him, "What's BH?" mistaking the Cyrillic letters of his monogram for Latin letters (in full, his name is something like Виктор Наворски in Cyrillic). In a small way, her assumption that the letters are Latin matches what she says about herself shortly before this: "I always see men the way I wanna see 'em."
Later, the two meet by chance in Borders, where Amelia is buying a book about Napoleon. She tells Viktor that Napoleon is "one of my favorites," and Viktor subsequently develops his own interest in Napoleon. His primary motivation seems to be a desire to have something in common with Amelia, but he may also identify with Napoleon because their situations are similar. Amelia tells him, "After he loses the Battle of Waterloo, Napoleon isolates himself on the tiny island of St. Helena." (According to Britannica, Napoleon became a recluse while he was exiled there, so this is isolation even within confinement.) To some degree, Viktor is also isolated because he's stuck in the terminal.
