Why didn't the Vampire Hero even bother with the civilians when the Fist Hero and the Murim Hero were already enough? Was the Mech Hero busy as well? There was no reasonable way the Magic Hero could have escaped with the Spear Hero in a scenario that takes everything into consideration, also they have the Returnee Hero, unless they specify later that he let them go or that he has a strict limit to his time travel (which I'm doubtful there will be any) the story of the Spear Hero would have realistically ended here.
Times that the Spear Hero should have died: 2
