  We present generalized parton distributions for weakly bound systems on the
light cone in order to build intuition about the light-front formalism. Physics
at the crossover is reviewed in terms of the light-cone Fock space
representation. Furthermore, we link light-cone Fock components to the equal
(light-cone) time projection of the covariant Bethe-Salpeter amplitude.
Continuity of the distributions arises naturally in this weak binding model.
