- However having to have his name as a nod of the show's director, it is unknown if he voiced by him.
- That being said above that when he was seen dating with that said woman, who coincidentally looked similar to the unnamed wife of Brown-Haired Guy, unknown whether that woman is either separated or divorced within the latter or was either cheating.
- It is not known whether that woman was still with the other guy as in later episodes which is questionable if its breaking continuity.
