Quote #7
If she'd healed me, there was no telling what shape she could be in now. Her moods and magic were linked, and this had been a pretty intense show of magic. (18.68)
It turns out you can't just go around using magic and not having any consequences, and this passage reminds us that even though Lissa is a vampire, she's still kept within the confines of the Morois. They are not as strong and powerful as the Strigoi (although it's a trade-off since those guys can't use magic at all).
Quote #8
"The trauma you've experienced since the accident comes from more than just your family's loss. It's from using spirit. The accident woke the spirit in you; your fear over seeing Rose dead made it burst out, allowing you to heal her. It forged your bond. And once it's out, you can't put it back. It's a powerful element—but it's also dangerous. Earth users get their power from the earth, air users from the air. But spirit? Where do you think that comes from?" (22.38)
Victor explains the psychic bond and healing powers to Lissa. It might sound creepy, but we've seen this throughout the whole novel. Step (1) Lissa heals something; step (2) Lissa gets depressed and flips out.
Quote #9
Then… it was like… I don't even know how to describe it. Color and light and music and life and joy and love… so many wonderful things, all the lovely things that make up the world and make it worth living in. Lissa summoned up all of those things, as many as she could, and sent them into Victor. The magic flowed through both of us, brilliant and sweet. It was alive. It was her life. And as wonderful as it all felt, she was growing weaker and weaker. (22.63)
Check out the way the healing is described—it's magical alright, but not in the waving a wand type of way. Lissa is somehow harnessing her life and pouring it right into Victor. It's pretty magical, even listening to the description.
