Tiny Green Leaf

[Zeus]

Hi, all - my old girl Phal is in the middle of her shed/new growth phase. This happens as soon as the weather gets cold and the sun’s angle changes. She will drop a few of her bottom leaves and grow new ones mid-to-top crown just before popping one or two flower spikes in late Dec or early January. She does the same with her air roots. This has been going on for more than 4 years and, for her anyway, is completely normal. When finished, she’s healthy and green and ready to grow a huge number of blooms. I just let her do her thing and remove the leaves/roots once I’m sure they’re completely gone.

Today, though, as noticed a tiny healthy green leaf growing from within the potting medium (bark) and is maybe 3 inches away from the base of the crown. I can’t yet tell from where it’s coming but assume it’s a little sprout from hidden roots under the surface.

This can’t be a keiki correct? Don’t usually come from the main area of the plant?

Picture attached. Thanks for any thoughts or ideas.
