I was just watching TNG "Lower Decks on BBC America (why is it on BBC America? One Brit qualifies a series?).
The character of Ben in 10 Forward, in his mannerisms and how he acts, seems a whole lot like Guinan.
I think he does a great job with the character, but it soooo feels like Guinan in the way he coaches people into talking to each other...the way Guinan does it.
It's a shame we never see him again...not even on DS9.
