Very weird subwave... how to treat it?

So this recent sideways wave is really weird. I've counted it as minisubwave 2 of subwave C, but it looks weird.

Here's what it could be:
1. It hasn't broken the rules of a minisubwave 2, so it could be a very long and sideways minisubwave 2 of subwave C
2. ABC could have finished very shallow, and we could be going sideways before continuing the wave up
3. We are on subwave B, and Subwave C hasn't started yet
4. something else?

Suggestions?
