On this occasion, Ariel and his co-year from Nigeria, had a chance to speak (in Italian) to hundreds of kids in Sala Nervi, Vatican State. He spoke of his essay, selected by UWC Adriatic (UWCAD), on Cos'è significa la pace per i bambini del Timor Est? or What does Peace mean to children in Timor-Leste? In his essay, he explained how the absence of war does not always bring peace. However, to him, peace is when children can go to school; eat and enjoy their childhood; are not obligated to work; and are not being subjected to any form of violence. 

He also presented Timor-Leste culture by wearing his national costume. Many have not heard of Timor-Leste, so he had to give a brief introduction about Timor-Leste which he described it as a small island in South East Asia located next to Australia. 

His essay is included in a printed copy along with other essays from his co-years on Armenian Genocide, Nigeria, Egypt and Mexico; which was later given to Pope Francis.

It was just like a dream; which became true for him!
