looks like a basal keiki. i would leave it there, because it will eventually spike and then your plant will have an even bigger show. i dont know why you would remove it or how, i have never had a basal keiki
no problem. like i said, i never had a basal keiki, but i have seen some lovely phals with basal keikis in bloom they are gorgeous if possible i would keep it on there
Sometimes Basal keikis for if there has been damage to the crown of the main plant. It kind of looks from your pics as though the newest leaf in the crown had some problems but is now recovering and that could have caused the basal keiki to start.
As others have said, if you get both flowering together it can give a great display.
