Happy was always a jackass and you were always stubborn. Everyone knew not to have you in a room for longer than 10 minutes together otherwise things got messy. Nobody knows how messy though...
You and Sam are now doing things you never expected. Get into arguments that were thought to never be possible. Lose people you would never want to lose. Enemies return and don't leave. You risk your life, and lose the one you love most. You leave the world and find another. People are now back, while other are slowly going.
