I also feel that Phlox had made the match by pairing Trip with T'Pol. A lot of passion was there and some strange aspects like that telepathic white room their bond sent them in. Other times, it was very down to earth, like when they dealt with their cloned child. There was never any rhyme or reason to any of it, they just had a bunch of random stuff happen over the course of their relationship and in some ways, perhaps ... it leant itself to a certain realism, that way. But they looked great together and were totally believable as young lovers.
