I like thinking through this chapter from Clark's perspective. Lois has been feverishly searching for him for weeks, so while it's a surprise to suddenly find him, it's something she's thought about a lot. But from his perspective, he's been spending those weeks feeling guilty, terrified, and more alone than he felt before. And suddenly she shows up and he can't believe it, and he tries to push her away but she won't go, and he tries to pull away but he can't overcome the magnetism of the possibilities her presence brings. He is going to be a force of nature once he believes and puts his energy into fighting instead of running.
