I'm betting he won't make it. Hope I'm wrong, but when they leave their tubes, it's not good often. Blowing a crown (feathers) is one thing, but when the whole worm is out and not hidden somewhenre already working on another tube, the outcome is doubtful. Didja have it in a heavy flow area that it may not have liked? They will leave and start anew sometimes when that happens and it could be months before you see it again.
