I dont get why Malcolm would...
continue to go undercover as Hattie.
If i was Hattie, i wouldnt allow him to use my full name and persona to do "dangerous" police work. What happens if some bad guys find out about this disguise he uses so frequently, go looking for "Hattie" and kill the real one instead? Theres no reason he should still be using her anymore but hollywood loves when a man (especially black men) put on dresses for comedy.
Reminds me of that madtv sketch that featured all black actors from movies where they were dressed as women (eddie murphy-mama klump, wayans bros-white chicks, tyler perry-madea, martin lawrence-big momma).
