I bet when Denise heard about the MU episodes of DS9, she thought, "aw man...why didn't I think of that for me during the TNG years?!"
That would have been interesting to see Denise & the rest of the TNG cast in a MU episode. I know there are TNG MU books, but episodes would have been fun too. As a matter of fact, it would have been neat to have seen some TNG characters (even a minor character like Barclay) in some of the DS9 MU episodes. Kinda like they did with Mirror Tuvok!
