Warning: Contains potential spoilers for Bloodline: Daughter of Blade #3!Brielle Brooks, the daughter of Blade, is following an important rule from the infamous vampire hunter's eponymous 1998 film. In a first look at Bloodline: Daughter of Blade #3, Blade meets his daughter for the first time in years, just as her own vampiric background begins to assert itself. He shows her the ropes, training her in the art of combat–and gives her a serum to control her bloodlust, not unlike Blade himself took in his first feature film from 1998.

Marvel Comics has provided a special first look on its website, including a look at unlettered preview pages, shared below; the issue will be written by Danny Lore and drawn by Karen Darboe. The first page flashes back to Brielle’s birth before returning to the present day, where she finds herself not only in the grip of bloodlust, but fighting her father as well. Blade injects his daughter Brielle with a special serum that instantly calms her down on the next page. The page following shows Blade doing what he does best: killing vampires. Father and daughter share a moment in the final page, where Blade shows Brielle how to fight with a sword.Related: Blade Explains the Shocking Secret Weapon to Killing Marvel's Vampires

Long-time fans will recognize the serum Blade injects into Brielle. In 1998, Marvel scored its first hit at the box office with Blade, starring Wesley Snipes as the titular character. In the films, Blade is a daywalker, much like he is in the comics; however, the filmmakers added an element of their own: a special serum that Blade had to take in order to curb his vampiric bloodlust. Now this serum has found its way into the comics, where Blade uses it to calm Brielle. The serum works, and Blade is free to have a moment with his daughter.

Much like her father, Brielle has vampiric heritage, and with that comes the urge to feed–an urge often expressed through violence and sheer force. In this preview, Blade uses it to deescalate the situation without having to hurt Brielle, and this represents something of a change in approach for the vampire hunter. Blade stalks his prey ruthlessly, countering their violence with more violence–yet the serum represents a whole new method for Blade. Did Blade use the serum only because Brielle was his daughter? Or could Blade perhaps be rethinking his strategies, especially now that he is a father? Given Blade’s actions in the rest of the preview, it seems unlikely he is altering his methods, but the serum still represents a new way of thinking for him.

The presence of the serum also raises questions of its own: did Blade create it? And can it calm the bloodlust in anyone with a trace of vampirism, or did it work only because of Brielle’s unique body chemistry? If it could be applied to other vampires, it could represent a massive step forward in dealing with the vampire menace, which is growing by the day in the Marvel Universe. This serum, which first appeared in Blade’s 1998 movie, has now entered the comics–and could be a potential game changer.
