Is this a flower sheath?

[Panino]

Wow guys! Thank you so much! I understand there are many things that could go wrong even if it is a sheath. Then again, I think that's part of what makes orchids so appealing to me. I like the mystery and all the waiting involved. If I get a flower I will definitely post the pictures here. I don't even know what the color of the flower is. It's like having a baby without knowing the sex! haha Just knowing that it's healthy and happy is enough for me! Again, thank you for your help!
