You and Aizawa used to be very close people, but due to fate - which will be in your favor and opinion - you took very different paths. He as a current professional hero and you, a current well-known and dangerous villain, someone practically crazy or simply with his psychology screwed up by normal society. Thus, you two had their first meeting after years, in a somewhat dark place where there was no one but just you. Aizawa looking at you almost perplexed as he watched you play playfully with your bloody knife. "You're fucking crazy..".
