Because this clearly of the BDSP promotion in the anime so it would make for both Dawn and Cynthia to return considering there literally in those games.I highly doubt Dawn returns for this arc. Why would she return so soon after her cameo? I think friends means Goh & Chloe. Cynthia might come along.
I fail to see why just because Dawn showed up in episode 74 & episode 75 that it should somehow prevent her from showing up here.
Now it guaranteed that Dawn will show up here? No, but it’s certainly a very realistic possibility.
