The scene is #600 is weird because there is no hint about it at all before. In fact, Jean was shown to be in love with Scott several time in the previous issue. And even in this issue, she tell Scott that if she want to take a break from the X-Men, it has nothing to do with him. But Hank feel that everything is his fault. That his adult-self broke the space-time continuum, that the X-Men will never exist because of him and that everyone was blaming him. I got the feeling that Jean mostly went after him to reassure him that it wasn't the case. That she was "fond" of him (her word). That they werent blaming him for what his adult-self did and that she wasn't taking a break because of him.
