I agree with Daisy, these plants tend to be just fine by themselves, excess water without roots to take it up really only affects them adversely.
The new growth looks like it might have been an attempt at a flower, which got aborted when the plant could not provide for its full development. This can also happen on fully rooted plants when they encounter adverse conditions after starting a flower. I see that often enough - the plant is just allocating its limited resources to what it needs most.
