After one of Buzz's hyperspeed testing runs, he returns to find that Alisha Hawthorne has gotten engaged. "What's her name?" Buzz asks, implying that Alisha's same-sex attraction has never been a secret to Buzz or anyone else. Her name, Alisha says, is Kiko. Later, we see the two women kiss to celebrate their 40th anniversary.
Even though Buzz laments the fact that everyone on the ship is marooned because of his mistake, Alisha tells him, "I wouldn't have met [Kiko] if we hadn't gotten stranded."
After one of Buzz's next testing runs, he returns to find that Alisha is quite visibly pregnant. How Alisha is pregnant, given the fact that she's married to a woman, is never explained.
Buzz's last testing trip, as noted, correlates to more than six decades of time passing back on the planet, skipping an entire generation. We then meet Izzy Hawthorne, granddaughter of Alisha, who refers glowingly to her "two grandmas."
I'll return to some of the important implications of this same-sex relationship in the Conclusion.
Wokeness is so woke its woke for wokeness sake
