There's another stem that has come up, and it's a completely diff plant, go figure. fancy leaf is the one on the left, their in the same pot.
Fancy leaf Platinum and what the heck else LOL
Platinum constantly sends up non-variegated shoots. They are much more vigorous than the variegated form, they do root, but often become variegated again.
I'd just remove it as low as possible and move on.
