I love that that most main characters in these books are either children or single adults. or an adult in a dysfunctional relationship. You can really hc every sexuality for these people
Tanc and Tracy kissed, but they make such good comphet because of the tropes they embody
Lauren and Lysander also can be hced as comphet, but more as in they thought they needed to date because they were such good friends
The Thunderbird handholding scene kind of robs them of their plausible deniability but the canon teen crushes are all so low-key that I think you can get away with pretending they weren't there for a fic. same for Charlie and Matilda (or Dagbert)
Most of the kids do of course have two parents in a het relationship, but we're never shown much of how those work beside Amy and Lyell
Mr. and Mrs. Gunn could just be good friends who thought they should hook up because of it. Mr. and Mrs. Silk could divorce and I wouldn't be surprised. The Torssons and Sages seem functional though
I would fully accept that Harold had never loved Dorothy, and Venetia and Natalia could also full on be compheting
Treasure and Pearl's "sweetheart"'s genders aren't specified
and Katya, Christopher, Alice, Eustacia, Lucretia...
We never see Ezekiel and his wife. or James. Or Maisie's husband. just saying.
also. if they ever adapt cotrk, they should keep it that way. no romantic relationship drama for these kids let them fight the generational trauma. that's enough
