$v_{3}\{2, |\Delta\eta| > 0\}$, $v_{3}[2, |\Delta\eta| > 0]$, $v_{3}\{2, |\Delta\eta| > 0.8\}$ and $v_{3}[2, |\Delta\eta| > 0.8]$ for various multiplicity classes in p--Pb collisions at $\sqrt{s_{_{\rm NN}}} = 5.02$ TeV. Hydrodynamic calculations (MUSIC)  with modified MC-Glauber initial conditions and $\eta/s =$ 0.08 for $v_{2}\{2\}$ and $v_{2}[2]$ are shown as solid blue and dashed red lines.
