In this issue, Villalba-Galea (2023. J. Gen. Physiol. https://doi.org/10.1085/jgp.202313371) expresses interest in our recently published work (Cowgill and Chanda. 2023. J. Gen. Physiol. https://doi.org/10.1085/jgp.202112883). Our response points out the deficiencies in the alternative explanation proposed by Villalba-Galea to account for our findings on hysteresis (or lack thereof) in steady state charge–voltage curves of Shaker potassium channel.
