A lot of people have been commenting on how it was stupid that the Juubi knew exactly where the HQ was. This was actually shown in this chapter, but it was just kind of subtle. On one page, the communication blob was shown to start splitting and turning spikey. There appears to be a rinnegan inside it too suggesting the Juubi tapped into their communications and located them. I missed this the first time through.
The Juubi is looking better now, but still really weird. It looks a little closer to the Geddo Mazou statue. Maybe it still has further to go?
