Another hot take. Peacemaker and Economos are much more interesting as a couple than Peacemaker and Harcourt
I think one way Chris could grow as a person would be to show him growing beyond his physical attraction to Harcourt and beginning to see her as a person and a friend (as we recall, he has issues with sexism)
John and Chris work together much more interestingly because of their similarities. Both suffer from toxic masculinity to varying degrees, as well as deep insecurities. Their relationship evolves from colleagues to "enemies," and then John regains Chris's trust, and Chris even begins to admire him
There comes the "what if" section!! In season two, the boat scene would have been SOOO interesting if it had been Chris x John. They walk around, even become somewhat closer, go to a performance by a band they both like, and bum they kiss. John is in shock, he's having a sexual identity crisis, and he never even considered the possibility that he might be attracted to men, so of course he runs away, scared. Chris is also in shock he knows he's bi but Economos of all people?? So here they are, two grown-ups, John working at Argus and even having to keep an eye on Chris, whom he's trying to avoid, while Chris slowly begins to accept the situation and try to figure things out, just like in canon. And it's all so bittersweet
But it's a shame this is just a thought and there won't be any content because Economos isn't a twink and he and Chris are middle-aged men
