Well they needed a whole week for just "the prologue" so equal amount of time to wrap up all relationships, politics, fallout, and endpoints is a fair estimation. However, if you do the math, my "at least" estimate gave 1 update for Week 3, 4 to Week 4, and then only 1 for the Conclusion, just in case all the story threads can be tied off quickly.Idk about "another week to wrap things up" lol, I've always felt like once the exhibition is over 2-3 days will be enough to close the story, tho who knows really.
