For Tommy to really be a mature creation, he needs complex emotions. With Dave, he feels jealousy. As Peri puts it, he's supposed to be like a loyal dog. But he doesn't like it when she plays with other dogs. He never gets violent or anything. But Tommy is clearly wounded and he is short with Peri when she tries to talk to him about it.
Devon loves children and sees an injustice in how Ellen and Richard are treated by most people. He proposes marriage to fix that, but also for his own purposes. If he can convince the authorities that he's a changed man (which we would just see as him being forced even further into the closet), he can go back to Scotland to live. At first, Ellen is afraid he's in love with her but she doesn't feel the same way about her. But they come to an understanding.
When Craig and Nell start off, they get off on the wrong foot. Nell and Dez abandon the others to follow childish pursuits. This leaves Craig and Mei-Lin lost in Brighton. Dez leaves Elise and Noah when they're foraging for food. Nell takes a nap and Dez does ollies on his skateboard. Craig reads them both the Riot Act. But Nell warms up to him, and comes to realize that he is pretty much the only person standing between the group and utter starvation and despair. The no-nonsense middle manager gets things done.
Apart from David, the only other person Carmen regularly calls by their first name is Robin. And so that has led me to wonder—did they have any sort of a romantic relationship? Did it go past psychiatrist/patient? I honestly have no idea, but the concept intrigues me. Perhaps I'll visit it eventually.
For 2022 NaNoWriMo, I have decided to create a prequel for each of the 5 main universes: Real Hub of the Universe, Obolonks, Time Addicts (while the Obolonks and Time Addicts are in the same universe, I just plain want to write two separate prequels!), Untrustworthy, The Enigman Cave, and Mettle. So, I anticipate a lot of fun and perhaps a little confusion. But it's all good!
Apart from having love interests in many of my works, I kind of don't have a continuity or Easter Egg for him. I love his memory, and may write a similar character in the future. Imagine Dalton's POV!
