>>33569199Brock was still part of the main cast back then, and Chronicles was still airing at the time, so Misty hadn't completely disappeared yet back then.
This is the first true "anniversary" reunion, for the show's 20th anniversary. Don't expect to see Misty again until the 40th anniversary. Brock though, his last appearance before Sun/Moon was in 2013, so he had only gone five years without an appearance compared to Misty's twelve.
