In Boruto: Naruto Next Generations Episode-55, Shukaku communicated with Gaara in the Tailed Beast/Jinchūriki void. If Gaara did make himself a Jinchūriki again, what would be the reason for that and why not just hide Shukaku in a heavily guarded region in The Hidden Sand Village or in The Land of Wind? Did both Gaara and Shukaku choose to be together again?
Also why did only Shukaku sense that something happened to Gyūki and not the other tiled beasts? Kurama should have been the first to sense Gyūki's chakra vanishing.
