Could be that what Wendy is sensing isnt even what's under the ice (or was...), maybe she's sensing whoever or whatever has taken or released the flame (I don't think Gray's the one that made the flame disappear, more like it was already gone and the ice was just a hollow casing).

As I think of it it's more unlikely its one of the dragons. Seeing as how Gray sensed familiar magic from the ice it could be something connected to Ur. There are very few people that use ice magic (I'm not saying the ice was done by Ur herself, more like herself/her magic was somehow gathered to form this ice barrier) it's not going to be Lyon, that's quite obvious. Not like he's going to go all Galuna Island on us again. Then there's Ultear, who I doubt could even cast such magic seeing the state she's in leaving Ur the only likely connection left.

As for what Wendy sensed I'm still not sure. DAMMIT CARLA, WHY CAN'T YOU USE YOUR PRECOGNITION FOR ANYTHING USEFUL. Like I said, could just be the new enemy. Then there's what Natsu sensed, "The Flame's Voice" as the next chapter says (What it leads me to believe) which is what made me think Igneel or Atlas Flame.

It's just one big clusterf**k of familiarities right now.
