I am Lane!!

"Does that mean that if I die…" 

"I will die with you." 

Lane revealed as she lowered her head, not looking into Nux's eyes.

Obviously, as Nux's shadow, she perfectly understood how much nux hated when he realized Evane's life was now dependent on him since she was forced to heal him putting her life on the line.

He considered it as exchanging their lives and hated the concept from the depth of his heart, this time, however, she had taken this a step further by forming her Law.

Rather than exchanging their lives, she directly connected hers with his, in Evane's case, at the very least, the woman could completely revive him once before she was forced to use her life.

If they ever encountered an enemy strong enough to kill them, Evane could use her powers, revive Nux and all of them could run away, her case, however, was worse.
