Our client still has some tics and fears after our Protocol session. What else can we do to help?

This is learned behavior. It must be unlearned. Your Protocol is working on the cellular memory that has been created by the presence of these beings manipulating the muscles and nerves. This is not a serious problem, it will fade in time if you keep working on this. It may require a renewed Protocol session to increase the level of intention of the healing requests ongoing. This will also do more karmic repair which is helpful for the fears. Once old karmic business has been stirred up by spirit meddlers bringing it to the attention of the deep subconscious mind, the mind itself may visit the akashic records, again and again, looking for further evidence and further links to the problem, to understand it better, and to deal with the uncertainty that has been created. Even when healed, the mind will remember its recent findings and may go back to look once again and stir up the problem anew. This is a liability inherent in spirit attacks, that the effects leave fingerprints, and act as a kind of impetus that carries forward with a life of its own. This is simply a combination of the intensity of the attack coupled with human nature being what it is—often fearing the worst and projecting forward in worrying about possible future returns of a prior calamity. The Protocol work will be helpful here as well.
