Agreed. *nods* Someone mentioned it, and I tend to agree that, at the point when Clint meets Nat he's already been with SHIELD several years. I suppose he just wouldn't be of much use to an organization like SHIELD if he continued to be completely fucked up. I like to think that he had time to heal and learned at least how to pick out the people he's going to trust. Besides, with Natasha's theme of reclaiming herself (and essentially healing) I like having Clint who has already healed to some degree (and knows about these things firsthand), which is why he's capable of being a stabilizing factor for her. But, when it comes to other people I think he's slow to trust, or very careful at least.
