In the collision of relativistic heavy ions, the energy densities are so large that a medium of deconfined colored particles is created. This short-lived medium cannot be observed directly but a plethora of signatures of this medium have been observed. Nonetheless, when bridging the gap between these large collision systems and small ones, a puzzle emerges: an azimuthal anisotropy, as well as other medium signatures, were observed in high multiplicity pp and pA collisions, but no jet quenching. In the present work, we investigate whether or not a small collision system could give rise to an anisotropy without substantially quenching jets by exploring the question of how many interactions it takes to modify a jet.
