Ok, let me clarify because this is more than a little frustrating for me at the moment and I wasn't as clear as I could have been. One, "others" was meant for less specific character dialog, i.e. greetings. Two, the duo referred to Riker and Troi, not any other characters.
Three, this removed the entire context of my original response that was commenting on another poster remarking about Sirtis possibly not returning (for whatever reason). In that context, I was stating that Troi and Riker shared similar roles as advisers and serving as Picard's conscience in difficult situations. Thus, the advice dialog could have been largely placed on Riker if Troi was not able to appear (again, for whatever reason Sirtis could not).
Nowhere in my argument was I suggesting cutting and pasting characters.
Now, I will leave it at that because I feeling really frustrated at the moment (for many reasons) and don't feel the need to add further less I say something I will regret later on.
