Silver (fictional)

"Did you have a dog? A lab. Yeah, named him Silver. After the... Lone Ranger's horse."

- Nate Heywood and Hank Heywood discussing Silver.

Silver was a Lone Ranger's horse in a television series.

Overview
At some point in his childhood Hank Heywood watched a TV series in which Lone Ranger's horse was named Silver. That inspired him to name his pet Labrador after it.

Decades later Hank used "Silver" as his e-mail password, indirectly referencing both his pet and the series. Nate Heywood tricked him into saying the name of the pat as a part of father-son bonding talk during the Time Bureau mission in 1973.

Behind the scenes

 * Lone Ranger's horse is indeed called Silver in most iterations of the franchise, including radio and television series, movies, novels and comics.
