I own neither the story nor the characters of Roswell.
The dinner they chose was fajitas for two, and it was excellent. Betty Ann had served it to them herself.
They appeared to like intense flavors in Tonopah. The good news, as far as Liz was concerned, was that the salsa was on the side, her first taste of it had threatened to blister her lips... and she had plans for those lips, in the immediate future. The good news for Max was... besides the anticipation... that was the best salsa he'd ever tasted, and he slathered it on his tortillas as he constructed his fajitas from the large black skillet that sizzled before them.
The flan appeared to have about a million calories per teaspoonful, and they savored it, eating it slowly with small spoons, Liz shaking her head in amused amazement as Max would add leftover salsa from the dinner to his. 'Maybe we really aren't the same species after all,' she thought in amusement. At least, it was amusing at first. But as she contemplated that more... she felt a vague disquiet.
She had reassured him... reassured him that it would make no difference to her... even if their chemistries weren't compatible... but that wasn't entirely true. She really did want it all. And all included to carry Max's children... not now, certainly... they were already in over their head or nearly so... but someday.
Max and Isabel and Michael seemed so... human, except for their powers... clearly a big exception, and their love of sweet and spicy. It really didn't seem reasonable to her as a biologist for evolution to work that way. It really seemed like, they were at least part human, and for that part to work with their alien part... well the chemistry just could not be all that different. So... how had that worked on the planet they were from... how had they evolved their powers?
Liz knew that her energy came from mitochondria and that these mitochondria had originally evolved separately probably as some kind of bacteria and that they had their own DNA.
Was there something different about the mitochondria in Max? It must be. And what did that say about any children they might have? In humans, the mitochondria come from the mother. They are in the egg already when it is fertilized and usually, there is no mitochondria from the father. So if their cells were alike, maybe they could have children... maybe whatever was different about him was ONLY in those mitochondria, and they could have children, children with no powers. Oh, sometimes SOME of the fathers mitochondrial DNA would get in to the egg... from the tail of the sperm... from the little organelles that made the tail move so the sperm could swim... but usually not very much... only one percent or so. So maybe it would work... maybe they could have it all.
Liz remembered the nights since their marriage. Max had been so patient, so sweet. She probably ought to have wedding night anxiety... but she didn't. The girl who'd always had a plan for everything had run off almost on a whim... and been married at sixteen because she loved him, certainly, but the love would have lasted... they could have waited. It was really, she decided, because the other options were worse.
Their parents had been wrong about them... they would have waited... if they could have waited together. But not now. She couldn't go back, wouldn't go back, couldn't even imagine it.
The nights she had spent in his arms had consummated her feelings for him. The love was now much too strong to deny, much too strong to put off. Oh yes, Liz Evans was going to have sex with her husband tonight... no question about that. But it wasn't because she or he were desperate hormone-driven teenagers... it was because she knew that it was right... like nothing in her life had ever been right before.
"Max," she whispered. "It's been a long trip... all the way from Roswell. Don't you think it's time we went to bed?"
