What is going on with the peas!?!

I don't know if I should be excited or disappointed.  The package said that they would grow 4 to 6 feet tall so I built a 7 foot trellis cage just in case.  One of them just grew 4 inches in two days to 7 feet tall and I don't see any sign of pods.  They keep branching and even the branches have made branches.  They are the crop that I'm most excited about and they may not produce... I will try again in the spring either way.  Here are some progressive photos.
