Jill

Jill (that was almost certainly not her real name) was Masque's other top lieutenant in 1914, alongside Jack and Juan Juarez. A Frenchwoman, she may or may not have had some kind of connection with Henry Atkins, who had a locket that was a rocket with her picture in his pocket. That aside, she was also involved in coordinating the anarchists' efforts in the siege of the Wapping safehouse and defending from the young Centurions' counterattack. Later characterised by Juan as very diligent and idealistic, she clearly had some doubts about Masque's actions and alliances during that crisis, as even after the bloody raid and the explosion that destroyed Dr. Mostro's transmitter and a number of her comrades, she still attempted to reason with Fernando Jose Salas del Monte, hinting, quite rightly as it turned out, that they were both being played by someone else.

However, she would never meet Fer again or get an opportunity to confirm her suspicions. During the lead-up to the Battle of Saint Haven, she shared with Juan her knowledge of the Saint Haven Citadel's layout, particularly the hidden passages, and thus identified herself as a threat to his secret plan to take down the Shadow Federation from within by taking advantage of the same. As such, after the Centurions' incursion there began and she helped Juan shut down Else Rommel's plane, Juan tricked her and her patrol into walking straight into Else's ambush. In the ensuing fight, she got melted to death. After Juan said some kind words about her on his return, she was duly forgotten about by the entire world.
