Same here. & from the next chapter's title, i guess that the sabertooth girl will pass her stellar keys to lucy if she doesnt joins fairy tail. + im interested to see how erza will react to that past character(forgot her name)'s declaration of her hate toward jellal.
Now that Sabertooth's guild master was shown, kind of makes sense as to why only the strongest are accepted. I mean look at him. The mans built like a freight train. Probably with some crazy magic to go along with all that.
