And yes, it is arranged in a way that it seems Arlecchino, Childe and Wanderer are gossiping with each other about the other harbingers.

ft. The Jester Pierro, The Captain Capitano, The Doctor Dottore, The Damselette Columbina, The Knave Arlecchino, The Rooster Pulcinella, The Balladeer Scaramouche / Wanderer, The Marionette Sandrone, The Fair Lady La Signora, The Regrator Pantalone, The Childe Tartaglia.
