Behind the scenes

 * Her name as Janet was revealed in Combat, but the rest of the team were oblivious to Jack's naming of her. He later used the name "Janet" to introduce the hidden Sleeper to her. Janet was still credited as "Weevil", even after her name's revelation.
 * Beyond the name, there is little to indicate whether Janet was, in fact, a female Weevil, and the character was played by a male actor.
