True Lucy's kindness and trust in other's has to be also Layla's trait,so i bet it's a misunderstanding.An imposter killing Grammy is also possible,though we don't know if Gemmini was at the time also Laylas spirit.We know that Layla needed all the keys to bring the dragonslayers to the future,but there could be other CS mages be involved in this as Eclipse Plan after GMG indicated.So Layla has maby also rivals?
