  In Huybrighs et al., 2020 we investigated energetic proton depletions along
Galileo's Europa flyby E26. Based on a particle tracing analysis we proposed
that depletions are caused by perturbed electrogmagnetic fields combined with
atmospheric charge exchange and possible plumes. One depletion feature
identified as a plume signature was shown to be an artefact Jia et al., 2021.
Despite that, here we emphasize that Huybrighs et al., 2020 demonstrates that
plumes can cause proton depletions and that these features should be sought
after. Furthermore, the conclusions on the importance of perturbed
electromagnetic fields and atmospheric charge exchange on the depletions are
unaffected. We suggest that the artefact's cause is a mistagging of protons as
heavier ions by EPD. The artefact prevents us from confirming or excluding that
there is a plume associated depletion. We also address comments on the MHD
simulations and demonstrate that 540-1040 keV losses are not necessarily
inconsistent with 115-244 keV losses by plume associated charge exchange.
