@jebonaventure They're not interns, interns always wear green. The ones in yellow are production assistants, like Oliver, Emily and Marcus in All Stars.
If I'm not mistaken these are the same guys who appear for a glimpse in the CoC finale and are based on real people working on the show.
@CentroLeaks So we got 5 queens on performance or contest:
Kanto Queen Chloe (I know but she looks good on May’s outfit)
Hoenn Queen May
Sinnoh Queen Dawn
Kalos Queen Serena
Paldea Queen Liko
