I don't remember the exact words.
I watched it again, and the complete sentence is:
Tony, I'm glad you're back at headquarters. I don't want you to stay in your big house all the time. We all need friends and company. Now that The Avengers is yours, you are more suitable. /kloc-started at the age of 0/8, and never really integrated into any place, even when I was in the army. I believe in individuals, and I am glad that they have never let me down, so I can't let them down (referring to the imprisoned American team, and later Steven went to save them). I know I hurt you. I didn't tell you about your parents because I was afraid of hurting you. Later I found out that I was afraid of hurting myself. I'm sorry, I hope you can understand one day. I really hope that we can reach an agreement. Anyway, remember, if one day you and we need help, I will come.
