Is Raffi character in this series or not?Maybe if this was "Star Trek Raffi", maybe we would have seen why she was "fired" (though not the correct term).
Again given the amount of time they gave to showing the Mars attack again and again; as well as many different views of Picards resignation; you would think they could spend a little bit more time focusing on other main characters in the series; and not making Raffi's reunion with her son (for example), just come in effectively out of left field.
It's also a bit disingenuous to have a character claiming she's clean, when just a few days before she was still smoking snake weed or whatever it is, and downing a large bottle of vintage wine.
A series should serve all the characters, not over serve the main character. (IMO).
