Warning: spoilers ahead for Titans season 4, episode 6.
Jinx may not necessarily be dead after Titans season 4, part 1's big finale. The climactic battle of Titans season 4's first half pits Nightwing's team, minus a humbled Superboy, against Mother Mayhem's Church of Blood, and the result is mostly disastrous for the hopeful heroes. Not only failing to achieve any of their intended goals, the Titans also lose Jinx to Mother Mayhem herself, stabbed through the gut and seemingly killed. Jinx appears unnervingly limp as Nightwing cradles her unconscious head, and the duo's earlier conversation, in which Jinx admitted she enjoyed her time with the Titans, felt like a tacit farewell speech.
Fortunately for fans of snarky British humor, Titans season 4 and Jinx may not be finished with each other quite yet. Despite her body showing exactly zero signs of life when the Titans midseason finale ends, Jinx's magic has performed minor miracles throughout the Church of Blood arc, and the extent of her capabilities remains mysterious enough for a resurrection, healing, or rebirth of some description. Alternatively, Titans has established the classic DC trope of Lazarus pits as a method of cheating death. If one such pit exists in Metropolis, a quick dip would likely spare Jinx's life.
Beast Boy Could Save Jinx In Titans Season 4
Jinx's death represents the least of the Titans' problems when season 4, part 1 closes out. Sebastian Sanger finally transforms into Brother Blood, and wields his newfound magic, forcing the Titans disappear. Whether the heroes have been killed or teleported to safety remains unknown, but the only exception is Beast Boy, who successfully transfers himself into the Red before Sebastian's spell takes effect. Beast Boy's survival means the onus is now upon him to somehow rescue the Titans, and the season 4, part 1 finale hints toward time manipulation as a potential answer, as Gar is shown hearing Superboy's words before he speaks them.
If Beast Boy can utilize the Red's power to reverse time, he may be able to prevent Sebastian's transformation and save his friends from Brother Blood's eardrum-splitting sorcery altogether. Wind the clock back a few seconds earlier still, and Gar could use the cosmic force of the Red to intervene in Jinx and Mother Mayhem's fight, warning his sarcastic friend about the sneak attack, and saving Jinx from a skewering. Jinx may have died before her fellow Titans vanished, but Beast Boy could kill two birds with one stone - or, indeed, save six Titans with one cosmic force - by rescuing Jinx alongside the others.
Jinx Hints She Survived Death Already In Titans
No one can truly know their final words until the moment arrives, but "f**k... not again" is certainly an unusual line to bow out on. Jinx's parting shot heavily implies that being seemingly killed by Mother Mayhem in the Titans season 4, part 1 finale is not her first brush with death. Jinx is still around to hurl amusing insults and lust over Superboy in Titans' present day, so if Lisa Ambalavanar's character cheated the afterlife once already, she can plausibly pull the same trick again.
Jinx's death-defying antics may connect to Titans season 3 and the afterlife train, in which the Bon Jovi-loving spirit of Alan Ritchson's Hank revealed a path back to the living world. If Jinx has conjured some means of predicting where this elusive bridge will appear in the black-and-white afterlife, she may find dying a more temporary arrangement than most. Should Jinx somehow save herself when Titans season 4 resumes, rather than relying on Beast Boy to fix everything, she and Gar could pool their powers to bring the other heroes back from wherever Brother Blood sent them.
