That is not an earthworm. That is a pest you want to get rid of it is some species of cut worm. They are not beneficial. So toss him off the plant to some other plant. Then put a collar around the base of the plant. Also you can make a moat and fill it with beer, that will get the slugs and snails and cut worms and they die happy.
some pictures of my others! hows the earthworm, i think he likes to get high. love these pics
That is one BEAUTIFUL plant! You are jackpot lucky. Make sure you take a clone, don't lose those genetics.
Congratulations,
