  Recently our group analyzed how the probability distribution for the jet
opening angle is modified in an ensemble of jets that has propagated through an
expanding cooling droplet of plasma [1]. Each jet in the ensemble is
represented holographically by a string in the dual 4+1- dimensional
gravitational theory with the distribution of initial energies and opening
angles in the ensemble given by perturbative QCD. In [1], the full string
dynamics were approximated by assuming that the string moves at the speed of
light. We are now able to analyze the full string dynamics for a range of
possible initial conditions, giving us access to the dynamics of holographic
jets just after their creation. The nullification timescale and the features of
the string when it has nullified are all results of the string evolution. This
emboldens us to analyze the full jet shape modification, rather than just the
opening angle modification of each jet in the ensemble as in [1]. We find the
result that the jet shape scales with the opening angle at any particular
energy. We construct an ensemble of dijets with energies and energy asymmetry
distributions taken from events in proton-proton collisions, opening angle
distribution as in [1], and jet shape taken from proton-proton collisions and
scaled according to our result. We study how these observables are modified
after we send the ensemble of dijets through the strongly-coupled plasma.
