Continuity mistake: Barb's eyes are green throughout the movie, but when Chucky stabs her in the eye, the eyeball that rolls down the steps is blue.

Ending / spoiler
Directed by: Don Mancini
Starring: Brad Dourif, Alex Vincent, A Martinez, Danielle Bisutti
The police find come to Nica's home to find her on the floor of the elevator after her fight with Chucky. The next scene shows Nica in court ruled guilty of the murders that occured and her being sentence to serve time in a institution for the criminally insane. The next scene is Alice walking into her grandmother's home to find Chucky sitting on the table. When Alice asks wheres her grandmother, Chucky responds "in the cellar." The scene ends with Chucky and Alice playing "Hide The Soul" and Alice's grandmother popping up from the cellar, presumably interrupting Chucky's transfer.
Trivia: Had the longest timegap between sequels, coming out nine years after the previous film, "Seed of Chucky." The long wait was in part because a few years after "Seed" was released, several attempts were made to remake/reboot the series, given the rising popularity of 80's slasher-film reboots. Despite several false starts, the reboot never happened. Eventually, series creator Don Mancini opted to instead perform a "tonal reboot" of the series with this film - by setting it in the same "universe" as the other movies, but shifting the focus back to classic horror and delivering a film more tonally similar to the original 1988 film. Mancini wanted to please fans, who expressed interest in seeing another "scary" Chucky movie after the previous two films had become increasingly comedic in tone.





Answer: It's not any problem and trouble in the film. Maybe it's just a reflection of light in the bed.
