The stream is reliably detected to a declination of $-38^\\circ$, bringing the total known length of the Orphan stream to $108^\\circ$. We find a slight offset or \"S\" shape in the stream at $\\delta \\simeq -14^\\circ$ that would be consistent with the transition from leading to trailing arms. This coincides with a moderate concentration of $137 \\pm 25$ stars (to $g = 21.6$) that we consider a possible remnant of the Orphan progenitor.
