If it turns out that correcting that stitch is impossible or a huge pain, you may want to consider putting in a lifeline every fews rows. That way if it gets messed up, you can just rip out to your lifeline and reknit. I've done a lifeline before when the stitch pattern is just too difficult to tink back - - it's faster to frog and reknit than tink (and less frustrating!).

You can also string your lifeline through the hole in the needle if you are using the interchangeables that have a hole in the base to tighten the cable. If you do that, though, you need to use split ring markers so you can move them, otherwise they get caught and carried in the lifeline and can't move with the knitting.
