Do any of you have any experience with prayer plants?

I have one, and it is one of the few non-orchids in my household that are
surviviving, sort of.

I am wondering whether prayer plants can have keikis, because if they can I
think mine has one -- either that or it's been invaded by a little alien. It
has something that looks like a flower spike and then something that could
be a bundle of leaves at the end of the spike (only more dark than most of
it's other leaves are, almost black, and much smaller), and now it has two
roots growing out of this bundle. Seems like a keiki to me.

I have no clue what to do with it, so I may just wait and see for now.
