Crown Rot and New Side Growth on Angraecum Sesquipedale

[Maxxism]

Hey Everyone! I had crown rot and lost the top leaf on my Angraecum, now it looks like it's putting out a new plant from the side in between a couple of the lower leaves, (do we call this a keiki, or is that only when they grow from a flower spike?). Question is, what's best for this plant? Should I remove the new growth (if so, when is best, and how?), what about the mother plant? Will it ever recover from losing the top leaf? It looks kinda ratty overall, think it's just trying to make a new (and better start) with this new growth. Any guidance would be greatly appreciated. Thanks!
