Clint was silent as he walked , and wheeled her, He realized how close he had come to killing her, He knew he couldn't have coped if he did end up doing that.
He loved her so much.
"I....I realized how close I came to losing you and I don't know... Guess made me brave enough to say it." He wasn't sure why else. If it hadn't happened would he still have admited it? he wasn't sure.

When Natasha was finally discharged. Clint was glad to not be stuck around a hospital area. It was horrible being in such a place. He just wanted to get back to normal.
He was getting panic attacks and still seemed a bit tramatized at moments. He was buried under the covers of his bed seeming scared. He felt like Loki was going to come for him. He screamed when he thought he saw Loki but was imagining it.
