Too bad. Your reasons could be interesting. :( I myself don't see why having more than 3 keys should make her any less relevant to this arc or at least to Zeref and the Dragon King Festival unless of course she also pulled off summoning all the 12 Golden Keys. Whichever it is, I hope Layla is tied in to this arc or the next, as long as it is related to Dragons as well.
