>>91154681>she does not appear in enough episodes in a meaningful capacity to be considered main
To be honest I'm with other anon in that don't view being a "main" dependent on eps one makes appearances in either. Tom or Toffee for example are obviously more important than barely named extra #5 like Justin or Chantelle, even though the extra might technically show up in more episodes.
Jackie's featured in the show OP. It's clear Nefcy spent some time planning and honing her character herself, possibly even before the show production started in earnest, which means she's got some significance, she's not just one of the extras created by the staff.
This I think raises her into being a main, or one of the secondary mains if Star and Marco are the main characters. Imo her having been planned since so long gives her way more significance than Janna, for example, who's a last-minute extra who just got bumped into having more screentime for the sake of jokes, but whose role wasn't planned in the narrative since the start - even though Janna's had more screentime than Jackie
