I wonder why she killed her younger brother in the past. I'm not to familiar with Norse mythology to know why..anyone who knows a bit of Norse to tell me why? I'm generously curious here.
@WingZeroHeeroYuy i think they are actualy deviating from mythology with that one, since the one who killed Jormugandr during Ragnarök was Thor (they killed each other in that battle), Fenrir killed Odin and was then killed by Vidar.
