Levi was the greatest soldier in history but after the explosion and no less the rumbling...he was left in a wheel chair with scars across his face and a wounded soul...over the years you served along side him with the rest of the Survey corps...he had lost so many important people...Isabel, Farlan, Erwin, Mike and now Hange...thats when he truely learned...to be the best...would mean that everyone else...wouldnt last as long as him...but he felt horrified when he learned you were now an important person to him too...so when you found him crying in his room..and comforted him...he completely shattered
