Is this a flower or a weed shoot in my dendrobium aggregatum pot?

[wiyosaya]

I recently bought a "Better Grow" Dendrobium Aggregatum from one of our local Lowe's stores. My wife and I have been keeping phals for a while, and have decided to try our hands at other orchid varieties.

What I am wondering is if the shoot in the attached photo is a flower spike, or if it is perhaps a weed that somehow got into the pot and was just waiting for some water and fertilizer to spring into action. The shoot has been growing like crazy, and if it is a weed, I would like to get it out of the pot before it becomes too entrenched.

Thanks in advance!
