Avengers: A Maximoff story

Chapter 4

Wanda:
Vision flew us over to the jet. I found Dr. Banner awaiting us. He took Peter from my arms and rushed him in. Clint helped me put Peter on the stretcher. Bruce rushed him in and began to operate on him.
I sat outside trying to drown out the nosies coming out of Peter's room. I can't lose both of my brothers. I put my head in my hands and I cried. This was all my fault. It I hadn't convinced them to join, if I hadn't broken out of HYDRA months ago, if we never went to HYDRA. I should've caught him. He was right there. But I was too deep in disbelief to realize my brother could be falling to his death. But now all I can do is hope.
I continue to cry. I cry so much that I don't notice someone sit next to me. A make voice which I recognize as Clint says, "Hey, it's going to be okay. I'm so sorry about Pietro. Don't worry about Peter. He probably has a concussion. Bruce is the best doctor I know. He will fix him. Trust me. It's not your fault." I hug him. "Clint, what am I going to Do? I don't have a home, or any money to take care of Peter! The government will try to take us. What am I going to do?!"
He says, "Hey, you two can stay at my place. Only the others know about it. You two will be perfectly safe." "Thank you so much Clint." "Anytime."
Bruce walks outside with a clipboard. "Peter will be okay. He has a severe concussion. The experiments gave him the ability to experience everything ten times worse. So, loud sounds and pain would be worse for him. He should be up in a few hours. I'm sorry about your brother." I nod. "Thank you Doctor."
"You can call me Bruce, we are friends now."
"Thank you Bruce."
After he left, I went inside. Peter was asleep with some tubes in him. All his wounds were cleaned. I put my hand in his.

Why hadn't he told me about his spider senses?
