A deleted scene that shows Methos and Kronos on an unknown Greek island, the scenes were scripted and filmed, but didn't make the final cut of Revelation 6:8.
The scenes occurred towards the end of the episode when Methos and Kronos were looking down at Cassandra's cage. The submarine base is referred to as a "chateau" since Kronos' hideout was originally supposed to be a castle by the sea. When Highlander location scouts found an abandoned submarine base, however, a decision was quickly made to change the script.
The crew and cast alike were vocal in their criticism of this segment, no one thought it worked, and counted it a blessing that the episode ran long and it had to be cut.
