We had a little discussion about this a month ago and decided to have all the episodes in 2019 listed as season 3 due to how long it's been in between episodes and some other stuff, plus now it's weird that mtv.com says they were season 2 last week but this week is season 3. I believe they may have been intended to be part of season 2 but they waited 7 months in between to air them and airing it right up against "season 3" without calling it a finale or a premiere and only taking place a few days apart doesn't help either.
