Following the events of Final Crisis and Battle for the Cowl, in which Bruce Wayne has supposedly died and is replaced by Dick Grayson, Kate becomes the lead of Detective Comics from issue 854 to 863. In the first story, entitled "Elegy", Batwoman is seen investigating the arrival of a new leader of the Religion of Crime to Gotham. She briefly meets Batman (it is intentionally left ambiguous whether or not it is Dick Grayson or Bruce Wayne) to discuss her findings. Kate demonstrates greater knowledge of the Religion of Crime, and even corrects Batman by saying there's 13 and not 12 covens of the religion in Gotham. Batman concedes the case to her, and comments on the length of her hair (though panels on the same page reveal the long red wig hides her actual hair, styled short).Aspects of her personal life are also revealed, including her relationship with her ex-colonel father; serving as Batwoman's ally, whom she addresses as "sir." The strain of her late night vigilante activity has also taken a toll on her romantic relationships. Her lateness and night time absences are interpreted by her girlfriend as an on the side liaison with another woman. She breaks the relationship off as she believes Kate is not ready to commit to an exclusive relationship. A past traumatic incident is also alluded to which she claims still haunts her. As she vaguely describes the experience, her face is shown superimposed on the page over a restrained girl with a bag over her head. She later tracks down the new leader of the Religion of Crime: an elaborately costumed woman named Alice. Over the course of the conflict that ensues, Batwoman observes that Alice only speaks in quotations from Lewis Carroll, believing herself to be Alice Liddell. Alice denies a connection to the Mad Hatter.While attending a party thrown for the Gotham Police Department, Kate meets and flirts with detective Maggie Sawyer, and runs into her cousin Bette Kane (better known as the Teen Titans member Flamebird). Kate is apparently unaware of her cousin's vigilante activities, and inadvertently hurts her feelings when she cuts her off in the middle of a conversation to answer her cell phone. While dancing with Maggie, Kate discovers that Alice has kidnapped her father and plans to destroy Gotham by spreading a deadly airborne chemical from a hijacked airplane, thus succeeding where Mannheim failed. Batwoman boards the plane and defeats Alice's subordinates, eventually stopping the plot and rescuing her father in the process. However, Alice is accidentally thrown from the plane, only to be caught by Batwoman. Alice then shocks her by saying that Batwoman has "Our father's eyes," apparently revealing that she is in fact Kate's sister Beth (who was believed to have been killed years ago). With Batwoman stunned by the revelation, Alice stabs her in the wrist with a knife. Batwoman is forced to release her grip, sending Alice to her apparent demise in the river below.In the aftermath of this discovery, Kate locks herself in her crime lab and tries to come to terms with what just happened, while the police struggle in vain to find any sign of Alice's corpse. These scenes are depicted amongst numerous flashback sequences that comprise most of the issue. Throughout them, back story is provided from her childhood that depicts Kate, her twin sister Beth, and their mother being kidnapped. While Kate's father is able to rescue her, it appears as though both her sister and mother have been killed by the time he arrives.Batwoman appears in the miniseries Cry for Justice, a set-up for a new ongoing Justice League title. When the Justice League of America splits up following Bruce Wayne's death and a disastrous confrontation with the Shadow Cabinet, Green Lantern Hal Jordan leads a group of superheroes to Gotham in order to track down the supervillain known as Prometheus. Kate is shown stalking the heroes from the rooftops after they encounter Clayface. Batwoman later contacts both Leagues a
