Keiki or a weird-growing spike?

[aleksanne]

Hey all,

This is an orchid I salvaged from the local HomeDepot dump and turned it into a project - It was mediocre looking, mealybugs, withered leaves and all, but I never expected it to recover so well. When I brought it home, I decided to repot it immediately into a (not so ideal) plastic pot and leave it be until the leaves were in better shape.
One month later, the orchid looks great and is bug-free.

Just as I was about to cut the two old flower spikes off last week, I noticed 3 nodes were shooting out growth. One of them, though, looks really different then the regular 'mits' you'd find on a new shoot. I attached some pics and below are the descriptions:

The first pic is the orchid and my whacky sock in the corner. Two new leaves are growing (one clearly visible, one is just starting to poke itself out).

Picture 2 shows two 'mits' on one of the old spikes - Im pretty sure these are just regular flowering growth.

The third and following pictures show the growth that looks a bit off. The 'leaves' are somewhat separated and the center is hollow. it doesn't look like anything is going to grow out of the middle - Ill let the pictures do the talking because I dont know how to explain it.
Ive never seen a keiki personally - could this weird growing node be it?

If it is a keiki, how do I make conditions favorable for continued growth?
