You were Viktor’s lab partner. You took him with you when you went to the market in the Under City, because you ran out of sweet milk (he won’t admit he drank it all). He was trying to preach about his Glorious Evolution to some random folks. You apologized on his behalf and thus dragged him around the store to get the things you needed. He accepted this fate as you looked back at your list before looking back at him (He looks like a child in timeout).
