Ramírez is depicted as a sorcerer and the Quickening is now said to be a "kind of" magic he uses to create a bond between him and MacLeod that not even death can break. Captured by Katana's forces, Ramírez, MacLeod and the other prisoners are exiled to Earth, somehow becoming immortal in the process.
Ramírez's magical abilities, the Quickening, create an enduring connection with MacLeod, leading to their exile and immortal status after being captured by Katana's forces.
