Um, assuming that neglegable AC current flows from the grid circuit into
either plate or cathode circuit, and that the B+ rail has low AC impedance,
then, being a series circuit, how could the AC voltages at plate and cathode
be different, again assuming Rp and Rk are equal. I am also thinking that,
in this case, miller capacitance would not matter either as long as no
significant AC current flows through it.

This analysis doesn't include any parasitics, such as Miller capacitance.
