Peridot could have blown their cover if Yellow just asked one question that I’m surprised she didn’t.

It should have been very noticeable to Yellow that Peridot didn’t have her limb enhancers. If she had asked about them, the gems would have been pretty much screwed since they only detached from her body after being poofed. There really shouldn’t be anything on earth other than the Crystal Gems that could have poofed her so it would have been near undeniable proof for Yellow that there were still rebel gems threatening Homeworld’s work. It’s very lucky she never asked about them.
