I too am happy with this development. No one dies in One Piece either for the longest time and it was still one of the best manga around.

I think instead of last minute, he intended for it to be a out of no where surprise. Edo Lucy Tatoo is very different and i think hers is the only one that we see from all the Edo people while Lisana was the only one with a Fairy Tail tatoo.

We're still not 100% sure that she's the real Lisana though. It could be possible that this one is some sort of clone or whatever and that might explain the different spot for that Tatoo.
