The Grammy backstory doesn't add up one way or the other, because Layla never gifted those keys to her servants, but gave them away for savekeeping. All three of them should have given the keys to Lucy by themselves, but in the end it seems only Spetto really did, with Zoldeo going down the deep end and who-knows-what happening with Grammy.

But 2 out of 3 of Layla's "most trusted servants" making problems? Seems like she wasn't much of a judge of character. ^^ But with Lucy's decision to blindly trust Brandish in this chapter, it seems to run in the family.
