Clark's reaction and conditions were perfect, as was his timing. He gave her time and space to change her mind, which she didn't do on her own. I also found it amusing that she didn't listen to Lucy, Perry, Jimmy, or even Clark until he gave her an ultimatum as Superman.
I'm glad Perry backed up Clark. It's long past time she understood the consequences of her nuclear overreaction.
Clark's explanation to his parents of why he did what he did is concise, emotional, and poignant. Looking forward to finding out whether or not it's going to take a lot for Clark to trust her enough to even believe her apology is sincere.
