The only reason Odo eventually pursues it was after Odo, thanks to the future Odo that survives generations later in that planet the crew was stranded on, discovers his future self loses Kira to death before he got to tell her his true feelings. In a dark twist the Odo we knew became willing accept the outcome and continue being mum about the love he has hoping Kira's fate will be spared, but behind his back future Odo changed the flight plans to spare Kira Nyres life but end the lives of Dax, Sisko, and the other crew member's 8,000 descendants. If think about DS9, yeah was about Sisko but actually it was the story of a security officer of a Cardassian space station who never knew who or what he was but had this tolerable friendshp with a former Barjoran prisoner now eventual ex-terrorist that kept his existence through occupations as he slowly began to discover not who he loves but who he was and how he eventually becomes the solution to a climatic war and its end as he reconciles with an identity and his species he never knew existed. This was the longest story arc from episode one to the final episode where he literally became the happy ending for someone he never knew was of the Dominion and wound up with them back home.

Even in that strangely darker episode when Keiko became possessed and Miles had no clue what possessed her and even watched the demon or whatever it was throw his wife from the railing above the promenade which scared him to keeping his mouth shut about the possession. The most gripping time for that super couple and efinitely a great stand alone episode for the O'Briens had to be when Molly fell into a hole and came back a prehistoric teenager. That moment tested them more than any because Yoshi was kept away at Dax and Worf's until Molly became more civil but instead she stabs a man, and the grief of Keiko losing her baby girl to prehistoric jungles where she raised herself to avoid an arrest, thanks to Odo, then having the little Molly oddly crossed paths as if those days hours or years were merely minutes trades places of older Molly because Molly saw that pain of Keiko losing her as a toddler was a great moment for the supercouple. The Obriens had nothing but a series promotion in DS9 with these storylines-- from being in the background most of TNG's tenure. Good point about the Obriens, the only couple on DS9, well aside from Bashir and Ezri, to close out with a significant other.

That episode was hilarious, I did laugh when I saw what Zimmerman Jr. was doing--basically acting like a milder more engaging version of the Doctor that Bashir had to put up with. The other quirks and psychological process did have an opportunity to surface thanks to Seven being in sleep mode. The funnier moment was when she reappeared pissed, embarassed, and even looking like she was ready to grab some Pepto Bismal. Only problem with this who subject matter is that we forget this was not Ryans first opportunity. She did it even more hilarious with B'Lanna when she surfaces as the Klingon and Janeway hilariously says "Dont tell me those two finally come to blows?" A little girl surfaces later with Naomi, then the Vulcan with Tuvok.. the time after the diagnosis she even stretches her humanity side becoming unhinged screaming for someone to help HER. Yeah Ryan did her thing... better in that episode with a straight face told Naomi she can put her in a maturation chamber to expedite "perfectiveness." The seriousness of those like Seven, Worf and T'Pol makes their characters even more hilarious. T'Pol on Enterprise went full-throttle comedy mode with the Ferengis, later when Archer was tied up, and headed to the Expanse when Phlox was running the ship.
