You don't need prices to fall. You can look at month to month inflation or month over month. Eventually May to May will be small b/c the shock happened and that level become the new normal, but the ongoing rate went back down. Inflation can be very low and never have prices return to pre-COVID. You would need negative inflation, and likely a recession, for that to happen.
