Actually, that idea that the objects kept them in the barrier is really good!! Because it has already been pretty much stated that Igneel did something to Natsu's scarf (when Zeref attacked and it turned black) so this is very very plausible... XD Yay, another little piece possibly solved. And lol, maybe Gajeel's piercings or something like that holds a similar effect <- she can't think of anything else Gajeel has that could be from a dragon ^3^
