So a little more about Raffi... Just watched the Wheaton after-show where he interviewed Michelle Hurd and asked about Raffi’s background which she fleshed out with Stewart and the show runners. Apparently Raffi’s family were all involved with Federation activities and research and she was “raised by others”. She suffered from a kind of self-destructive guilt and was on her own for most of her life. Hurd made a big point about Raffi being an addict very early on - she drinks, she smokes, and Picard found her, bonded with her and brought her up out of her malaise, into Starfleet, much like Pike did with Kirk in NuTrek 2009. When Picard resigned, her world completely collapsed; she was extremely resentful and angry and it sent her back down deep into the hole where she started off.
I wish we got a little more of that backstory in ep 3, but it’s nice to know that it’s there, at least.
If her background isn't shown more in future episodes, it doesn't feel like it is there to me. Things like this has to be established on screen and not in an After Show many people don't watch.
