Remember that flashback where Baam asked Ha Jinsung to make him stronger in order to not have to say goodbye never again, while he is crying?

I think it's the strongest moment of desire shown in Tower of  God. That explains the difference in the evolution between Baam pre-Thorn and Baam post-Thorn or what is the same, Jyu Viole Grace and  Baam. I think after reuniting with his friends, Baam forgot how it feels to say goodbye because of the happiness blinding him.
