I wouldn't be surprised if Raven Tail left the city as soon as the their questioning was finished to hatch out new ways to discredit Fairy Tail and get their hands on Lumen Histoire.

In this regard I wonder if Flare might have left (the apology to Lucy might hint at a change of heart, along with getting beaten up by "Alexei") or been thrown out of Raven Tail (she was more of a liability than an asset to Ivan during the GMG).

As to the Spirits, maybe something special will happen if they all have the same owner. While they all did work together to close the gate, two of them were still Yukino's spirits.
