"We might not even have to go right to the source, just back to the classroom I was in. We were doing dissections, Viktor! We were literally cutting parts of them out! There's a fresh zombie liver just sitting at my work station."

Unless someone cleaned up...but she has a feeling no one's gotten around to that yet.
