Someone I knew a long time ago said that to me, too. The serum brought out the best and worst in us. He - Dr. Erskine - told me to be a good man. No matter what happened, he wanted me to remember who I was before, and to hold onto what made me a good person in the first place.
Yes. I can't put a finger on how I feel here. It's... not like anything I've felt before. I knew, before I saw him, when my best friend was here. I just knew.
