Wonder if you got a 'secondary' resonance in the unconnected
coil. If you had a voltage maxima or minima at the particular
point up the secondary in opposite phase with the actual
discharge...kind of a bi-polar coil done the hard way.

Have you tried feeding a signal of the same frequency that
your larger coil resonates at into the smaller secondary? You
could then probe the spot where the disharge 'stuck like glue' to
see if in fact there is a voltage node present.

Just my two cents worth.
