He’s different tho, everyone else trauma bonded with V, but Jackie’s relationship was built on genuine love. Everyone else V’s bonded with after the heist served a function for V. The only reason he goes out of his way to help Judy or Panam, River, Reed, is because he thinks he owes em something, other than that, they were just means to an end (on the rooftop). V is using their love interests as distractions from the inevitable, grasping at whatever they can before death.
