That extra isn't there and here are the differences in the pages:

The ending is completely different(I've read both). I've seen artists change panels when they release the tanko, but this is the largest change I've seen, going so far as to change the story. It's usually just touching up on images. I don't want to spoil the endings, but the scanlating group will be doing both parts, so we can wait for that.
I have the ebook version of this manga and the ending is different than the raws. Does anyone know if it's a difference between magazine and tanko, or ebook and tanko?
