This is Spriggie.
During my 3rd wash, (5 weeks in, May 2009) this little guy at the front decided it wanted to be free - and so it has released itself from the sister locking pattern.
My consultant tried to start him over but there's a mysterious knot in the middle so we've kinda left him as he is. lol.
Update: Since I wrote this, a couple from the back have also released themselves but not all the way to the root like ole spriggie did. I plan to leave them be for now.
