And right as the guard says that everest sees them and rushes at arc with a spear. right as he's about to get stabbed the guard comes in and takes the shot. the arc stands there as if it was his fault. and everest drips her spear thinking about what she just did.. As the guard is bleeding the arc touches him and he heals instantly. but when arc does that he passes out. so when the guard notices he grabbed arc as fast as he could and swam away..
