If the noonian singh centre for culural advancement's cold fusion reactor exploded atomizing Toronto, then alt Captain Kirk's Future happens.
If Kahn lives, then La'an's Federation happens.
If Sarah the Romulan, or La'an shoot's tween Kahn dead, then a third unknown future happens.
If La'an heads back in time and saves 90s Project Kahn, then the TOS Federation is back.
Yeah, I remember those things being mentioned by characters, but again, the episode rushed itself to the 20th century without barely any way to distinguish the timeline, other than "hey, who are you, you don't work on my Enterprise?". Everything felt rushed to get to the past so we could then spend endless scenes of Kirk and La'aan blithely traipsing around Toronto as if they were on holiday. I like those actors but it was so weird to watch them be suddenly pushed into a rom-com scenario.
