Im thinking about it and that hand can be of a slimmer person or a girl. So im ruling out, gildarts,elfman,Makarov. They all have rougher bodyshapes.
Also since the narrator is Lucy in the beginning im ruling her out. The chance of it being either Gajeel or Wendy is also realy slim since they are part of the dragon prophetic stuff.
Leaves it wide open realy, only clue is that Cana is crying extreme and Natsu is trying to hold it in.
So my asumption on that is that it cannot be a person closer to Natsu then Cana.
So lets say Lisanna,Gray and Erza are relatively safe. Cana would not be more emotional over these people then Natsu.
At the beginning *before the chosing of partners* i was like Macao could fit the bill, his death or seriously woundedness would definitly trigger this responce from both Natsu and Cana. Also since Macao took the heat for Cana before in arcs. But he isnt here *yet* and im not expecting him. Still he would have been best choice.
Cana isnt realy big friends with anyone else, perhaps Erza but i already ruled her out.
The only character i could think of that would make her cry like that is Mirajane. So for now ill go with her.
Mirajane, Erza and last Macao.
Thing is it could be Evergreen or Levi but then im asking. What is the function of Cana being so sad? After all this arc is suposed to be about her *thats what im getting from it*
Another thing thats maybe overlooked? Cana and Lucy have a long conversation, she says if she doesnt become Sclass she has no right meeting that person? What person?
