I've seen that Michael Michele (Dominique)'s social media accounts provide occasional details on the season's filming-in-progress. One gets the impression that she has the blessings of the producers, since no one's tried to shut her up.
Several people have said that the Liam/Fallon wedding should occur (or attempt to occur!) in episode four, but if Wakeema indeed doesn't appear until episode five, it means she isn't in the wedding party. This doesn't make sense, since she's supposed to be Fallon's BFF. Then again, they're also ignoring the absence of her brother Steven. [/grumbles] A photo Michael Michele released has the Colbys (Dom, Jeff, Monica) plus Culhane all dressed in black (and
very well-dressed in black, I might add) which has led some to think that they're decked out for a funeral, as if the events of episode four have caused Monica to return for a funeral in episode five. Of course it might have just been a coincidence that they're all wearing black. Having Jeff in the photo suggests he isn't the "guest of honor" at the possible funeral, but who else's funeral would be important enough for Monica to return?
