Loki smirked slightly, as his eyes started to glow. "Let me clear the way for you as well then." Gesturing out with his hands, the vines started to drop--pulled down by their shadows. Hands glowing green, Loki had ice come to cover them, and form walls, making a corridor and path of safety for Luz. As the vines moved to twine more around the heart to protect it, Loki shifted his attention slightly. Hands moving now, still glowing green with all the magic he was using between the shadows and ice, to act as if he were grasping the vines. To start pulling them away, and open, via telekinesis to give Luz a clear path.
