Unknowingly, Elle spent an hour just talking with Black Shadow in the Coffee Shop. He pestered her, asking a lot of questions regarding what happened to her two years ago- how she ended up with James, why law enforcement authorities declared that she died two years ago, and what she has been doing in the past two years.
Elle responded to his every query, telling him how she got injured and suffered from bio-weapon, how James rescued her together with Lu and how she tried to recover within the span of two years so that she could come back here and continue her unfinished mission.
They even talked about the new Catseye. Black Shadow shared his thoughts, thinking that Catseye was someone who was closed to her. That person was very familiar with how she worked before- copying her style of attacking her prey, torturing, and killing them slowly.
