lmao removed fan leaves will never grow back, i think you are confusing topping or removing branches to promote growth elsewhere on the plant, its never advisable to remove leaves, when yr plant has finished with a fan or any other leaf it will drop off by itself or come off with the slightest pull, if it doesnt come of with a slightest pull then yr plant still needs it! she will shed her own leaves when shes ready in her own time, and if you must cut leaves dont do it at the stem, doing this will only leave a wound on the main stem increasing risk of infection, leave a little stub of the petiole(leaf stem) on the main stem, this means the wound will heal away from the main stem, then the little stub will fall off a few days later.
