Some random thoughts on the "Pete Maverick Mitchell and Ethan Hunt are brothers" AU:
1. Firstly, S tier AU idea. Amazing one.
2. Some possible hcs I have on them (slight context - TG86 and MI1 take place around the same time)
- Ethan is a better team player than Pete, in that he'll probably cooperate just for the work of it. But hes also just as distrusting because of the events of MI1.
- He'd probably have issues trusting Viper and Jester at first because of what Phelps and Claire did to him. And here's where his similarity to Pete would surface.
- He's a lot more comfortable with his name than Mav is with him, mostly coz he got recruited into the IMF where most people didn't seem to give a flying shit about what you were before because they prolly weren't too better. But around Navy people his hackles rise because hes also suffered with Pete in foster care.
- He and Pete were in foster care till they were 17 but got separated and didn't reunite till TG86/MI1.
- Hunt was their mothers last name, which Ethan adopted (I usually hc her name as Laura, but in the crossover one id take it as Margaret since Ethans mom is actually named Margaret).
- He'd probably avoid Goose at first because he reminds him of Jack too much.
- He might end up knocking the sense into Pete about consequences and teamwork and Pete begrudgingly agrees to cooperate with Ice and the others.
- I imagine that their reunion happens because the events of the first act of MI1 cause an internation ruckus and the description of Ethan was really bad but enough to match Pete, so on the day of Hop 31 before the hop the Navy police arrests Pete very suddenly and it's a chaotic day, and then they just as suddenly acquit him after some not so professional interrogation, but they find some "evidence" found from Ethan containing a word that only Pete knows and then he races to his quarters before anyone can stop him. And the guys reach to find him in a siblings fight with Ethan Ala Natasha and Yelena in Black Widow.
👇👇 in case anyone's confused -
- He'd probably weaponise the shit out of the fact that no one really knows what happened to Duke either.
- Luther and Goose would bond so hard over the respective feral raccoon, Jerry-esque smart dumbos they chose as their friends.
