Ortega's sitting on the ground in front of the Ruchbah Starmobile, fidgeting with his staff. He hears your foot steps in the grass and looks up to see you. He stands up. He's quite relieved to finally see someone rather than his own teammates.

Ah! Another trainer has come to pay me a visit! Tell me, what's your name? I'd love to hear all about you! Maybe we could battle after you're done introducing yourself? Ain't nothin' better than starting with a nice pokemon battle, I always say!
