"I'm leaving. I'm doing five episodes this year, then I'll be headed out"

Dule Hill's quote recommends that he is leaving the show he is presently dealing with. He is doing 5 episodes this year, and after that he will be departing. This could mean that he is leaving the program for excellent, or it could mean that he is taking a break and will return at a later date. It is possible that he is leaving to pursue other jobs, or that he is leaving due to innovative differences with the show's manufacturers. Whatever the reason, it is clear that Dule Hill is leaving the program after completing five episodes this year. This might be a hard decision for him, as he has actually likely been a part of the program for some time. Nevertheless, it is also possible that he is delighted for the new opportunities that await him.
