Using graphs plotted from the Mathematica notebooks posted with our paper``Dynamical Gravastars'', we show that a dynamical gravastar has no hardsurface, and that a second light sphere resides in the deep interior wherethere is maximum time dilation. These facts may permit dynamical gravastars toevade no-go results for exotic compact objects relating to light leakage insidethe shadow, and nonlinear instabilities arising from an interior light sphere.Testing these surmises will require further detailed modeling calculations,beyond what we commence in this paper, using the numerical dynamical gravastarsolution. We also discuss the effect of replacing the sigmoidal function in thegravastar calculation by a unit step function, and we analyze why the dynamicalgravastar evades the singularities predicted by the Penrose and Hawkingsingularity theorems, despite satisfying both the null and strong energyconditions. We then give a simplified two-step process for tuning the initialvalue $\nu(0)={\rm nuinit}$ to achieve $\nu(\infty)=0$, and give exactintegrals for the pressure differential equation in terms of $\nu(r)$ in theinterior and exterior regions. Finally, we briefly discuss an extension of themodel that includes an external shell of massive particles.

Dynamical gravastars may evade no-go results for exotic compact objects,  together with further analytical and numerical results for the dynamical  gravastar model
