Yes, I've read that Mulgrew was quite upset when Kes was written out.
I haven’t been watching PIC but did read that Seven has been redefined as gay, something Jeri Taylor had originally pushed for. And I’m glad to hear that DISC has a homosexual couple. I just meant that in VOY, Janeway and Seven related as mentor / protégé. Disconnected and overwhelmed, Seven confesses to Janeway “I cannot function this way — alone,” and Janeway responds “You aren’t alone…I’m willing to help you.” And she does, sometimes going all out to save her.
PIC also had an interesting quote of recent (season 2), which was actually perfect in all ways, fits in easily, and was well-acted by Jeri (but she could make reciting the ingredients for making a fluffy water balloon compelling.)
From what I recall, it's something about wanting multiple people because it was akin to her experience in the Collective. Which makes sense and is very plausible. In a way, it's the best of both worlds... well, more than one way, too... 

Surprisingly good, and proves the show isn't a total mess the way some detractors say. (Okay, it's by no means perfect but the positives certainly don't hurt it.)
