My word, but this is an emotional story! Have tissues handy!
I loved both of these characters but Zeb...Zeb I understood, too! Not all of us are equipped to read the subtext of a relationship or have the role-modelling to enable us to speak of our feelings. And sometimes our best friends are the least able to help us, so it took opening up to Nick - who had not lived through Zeb & Chad's relationship and eventual breakup - before Zeb could see the 'other side'. And once he 'got' it, Zeb did all in his power to fix the situation!
