  Commencing with the composite fermion description of the $\nu=5/2$ fractional
quantum Hall effect, we study the dynamics of the edge neutral Majorana
fermions. We confirm that these neutral modes are chiral and show that a
conventional p-wave pairing interaction between CFs does not contribute to the
dynamics of the edge neutral fermions. We find an important bilinear coupling
between the charged and neutral modes. We show that owing to this coupling, the
dispersion of the neutral modes is linear and their velocities are proportional
to the wave vector of the charged mode. This dynamic origin of the motion of
the edge Majorana fermions was never expected before.
