If two electrons are in the same orbital they will always have opposite spins (they will be paired). If they are in two different orbitals they can have the same spin (be parallel). Electrons in the same shell, sub-shell, and orbital will never be parallel- they must have opposite spin values because it is impossible for two electrons in the same atom to match for all four quantum numbers.
