Renee leaves her suit up room complaining about a crazy woman and immediately runs into Soong. He promises to get her to safety, but when she starts feeling ill, he reveals he poisoned her with a neural toxin (when and how did he get that?). He leaves her to die, and she finds Jean-Luc. They watch as the Europa mission launches and "Renee" is revealed to be Tallinn, using her technology that disguises her as human to make her appear as Renee (would a neural toxin intended for humans work the same on a Romulan? I guess it could, but realistically, it probably shouldn't have). She dies, happy to have met the person she protected all this time. Soong returns to his lab where he trashes the place having realized he failed to achieve the outcome he wanted. Someone hacks into his system and erases all his data on his computer, which is revealed to be his daughter Kore (who apparently can do this with her VR goggles on a library Wi-Fi network), telling him it's for all her sisters. Soong pulls a file out of a drawer that says "Project Khan". Sigh... So I guess these writers are suggesting Soong created Khan, and now, rather than the Eugenics Wars taking place in 1996, it now takes place sometime after 2024? Meanwhile, Wesley Crusher shows up and explains to Kore he is a Traveler. Apparently the Travelers are also the Superior Beings that protects time and space that employs Supervisors like Tallinn and Gary Seven. He offers her a choice. Either she can live a normal life, or she can join him to become a Traveler, warning he cannot guarantee that'll be a safe path. Not having had a normal life, Kore chooses to become a Traveler, and they are beamed somewhere. Cool to see Wil Wheaton reprising his role, but this comes out of the blue and raises more questions than it answers. Doesn't really work with what the Traveler said his role was the first time we saw him in TNG. Not to mention, the last time we saw the Traveler, he'd told Wesley they don't interfere. Why is Kore even getting this invitation to join the Travelers? She hasn't displayed any special ability that we where ever shown. And what about Wesley's appearance in Nemesis, wearing a Starfleet uniform? Oh, and Wesley says that the last time he told a joke he changed a century of history... I'm not sure if this is meant to be a reference to something, but it doesn't make sense either way.
Seven, Raffi, Jean-Luc and Rios return to the Chateau, where they prepare to live out the remainder of their lives in the past. Picard returns a key to where he'll find it as a little boy and let his mother out of her room. Q congratulates him for choosing to maintain things as they were before when he could have destroyed that key. Picard asks "Why me?" and Q explains he wanted to help Picard know himself a little better and open himself to love, so that he wont die alone, like Q is about to... Um, what about Q's son? And why pretend to be Renee's psychiatrist trying to convince her to quit? Why did he get Adam Soong involved? What about "The trial never ends"? He did all of this simply as a "favor" to Jean-Luc so he could open himself up to love? You have got to be kidding me. Where is this idea that Jean-Luc couldn't open himself up to love even coming from? We've seen him have a few relationships during TNG. It was his duty to Starfleet or his rank that always got in the way, not some inability to love. Heck, he even had a wife and kids in "The Inner Light". Even if that wasn't real, it was still a real experience to Picard. At any rate, Q offers one last gift... Gathering everyone outside, Raffi threatens to kill Q, which he says in his weakened condition she might be able to do, but then he wouldn't be able to send them home. Rios asks not to be sent back, because he wants to stay in this time and Q explains that'll give him enough juice for one more surprise...
Back on the Stargazer, Picard aborts the autodestruct, having realized that this Borg Queen is actually the Jurati assimilated 400 years ago (why did she brute force her way onto the Stargazer? Isn't this supposed to be a kinder/gentler Borg Collective?). What happened to the Jurati and Rios that should still be on the Stargazer prior to Q's meddling? They've just disappeared. She explains she needs to commandeer their fleet so they can combine their shields to prevent a nearby anomaly from destroying the entire quadrant. And Starfleet didn't detected this until this exact moment.... why? At any rate, Picard gives Seven a field commission and she takes command of the Stargazer. Excelsior has some problems with their shields and when Raffi (I guess Q dropped her off on the Stargazer rather than Excelsior. tells them to reset, it's revealed Q's last surprise was to bring Elnor back alive and well (not sure why a Cadet would be responding though). The combine Borg and Starfleet shields successfully block a beam of energy the anomaly puts out (which they portray as only really threatening one planet that this collection of ships are easily able to block, it certainly did not threaten the entire quadrant like they'd claimed). The anomaly forms into a transwarp corridor unlike any Seven of Nine has ever seen before. Queen/Jurati asks for provisional Federation membership and that their collective of Borg will be gatekeepers for whatever is on the other side.
WHAT?! So, no let me get this straight... They suddenly introduce this "galactic event" capable of destroying an entire quadrant of the galaxy that this "friendly" Borg Collective, whom has stayed secret somewhere in the galaxy for 400 years, has suddenly shown up to ask the Federation for help to contain. This "galactic threat" then sends out a single beam, which is only about as big as the "friendly" Borg ship and is easily contained by the shields of about 30 ships. And then the "friendly" Borg ship is just going to sit there to watch over it? This is the laziest writing. It's literally only here for the sake of getting the Federation to work with the "friendly" Borg with no set up and then is wrapped up too quickly and easily. It doesn't feel satisfying or earned.
Back on Earth, Team Picard has a reunion with Guinan. She remembers all the events they just went through (wait... so the showrunner explained Guinan didn't remember the events of "Time's Arrow" because they came back in time from the Confederation timeline. But now that the timeline was restored and the Confederation timeline never happened, she still remembers that resulting time travel event? Which is it writers, you can't have it both ways). She tells Picard she's surprised he never noticed an old photo she has of Rios. Together they formed a clinic that helped a lot of people, and Rios was eventually killed in a bar fight, protecting medical supplies. The microbe Renee Picard discovered would be used by the Doctor's kid to clean the oceans and sky (well isn't that convenient?). Picard then returns to the Chateau, where he finds Laris has restored the solarium. She talks about leaving for her own adventures, but Picard tells her something about time not giving second changes but people can.
