Pope Francis hasn’t been one for papal protocol in his first year as the Holy See. On Wednesday, he again flashed his unpredictable side, when the popemobile was winding its way through the throngs in St. Peter’s square. Francis was aboard, doing normal Pope things—waving, blessing, kissing babies. That is, until he spotted fellow Argentine, and priest in his former Archdiocese of Buenos Aires, Father Fabian Baez. According to Catholic News Service, Baez called out to Francis and the pope stopped the popemobile and told Baez to climb aboard to go for a spin.
