Do you know what's worth fighting for When it's not worth dying for? Does it take your breath away And you feel yourself suffocating? Does the pain weigh out the pride? And you look for a place to hide? Did someone break your heart inside? You're in ruins One, twenty one guns Lay down your arms Give up the fight One, twenty one guns Throw up your arms into the sky, You and I When you're at the end of the road And you lost all sense of control And your thoughts have taken their toll When your mind breaks the spirit of your soul Your faith walks on broken glass And the hangover doesn't pass Nothing's ever built to last You're in ruins One, twenty one guns Lay down your arms Give up the fight One, twenty one guns Throw up your arms into the sky, You and I Did you try to live on your own When you burned down the house and home? Did you stand too close to the fire? Like a liar looking for forgiveness from a stone When it's time to live and let die And you can't get another try Something inside this heart has died You're in ruins One, twenty one guns Lay down your arms Give up the fight One, twenty one guns Throw up your arms into the sky, One, twenty one guns Lay down your arms Give up the fight One, twenty one guns Throw up your arms into the sky, You and I

The story is not making any sense, the mc is showing up his knowledge of the world but no one is questioning him I mean from what i remember ben didn't know anything about Vilgax until he met him but Mc is full on saying his name and no one is questioning from where did he get that name Mc is clearly saying Omnitrix name in front of max gwen & ben from chapter 2 but it is not asked how did you that what is this hero watch called utter nonsense.
