Lesson learned
In the end, Emma learned a lesson about how to deal with stress and her emotions in a more mature way. Sure, it is very tough to hear that your life is in danger due to cancer, but you need to stay strong and keep fighting. You cannot crumble and endanger yourself and others around you.
She learned that her actions were wrong and we hope that they made her a stronger person in the end. Chad did what he thought was right, but had regrets about putting Emma on blast later. We guess that in the end, the human side in us comes out and we just want people to be okay.
