Neither. The top growth will stretch, more nodes will form, more branching and fan leaves will grow from those nodes...
That fan leaf will always be right there, in it's assigned spot. New growth will grow above it, and you'll forget all about the undergrowth. (hopefully)

I used to worry about it many years ago. In the past I've trimmed them out of the way, twisty-tied them back, cut the fingers in half to allow SOME light to the undergrowth. But all that does is stunt the plant, and injure her unnecessarily.

Let her do her thing. She'll be fine. :thumbsup:
