@summerpipedream Pssst, so like, when Steve comes back after his 1800 trip instead of coming back to the same point of time he ended up leaving, why not have him come back a few years earlier? The original intent was for Watson to come after the whole ‘civil war’ happening. If Steve comes back during this it wouldn’t make much sense for it to be a happy reunion since he left Tony to freeze. Pretty sure love would be lost if anyone did that to someone that cared for them.
So instead have him come back long before the accords are presented. I’m thinking before Winter Soldier happens. Steve gets returned while he’s out jogging. All his memories are there, of Sherlock and John and Mycroft, and what’s about to happen soon in the near future and his LOVE for Tony. Right there and then he runs back to the Stark tower, barges in like a man on a mission, rushes to Tony’s floor and finds said man working on his bench with his back facing him.
“What can I do for you, cap?”
Steve doesn’t hesitate. He marches to his genius, grabs his face when Tony turns in question, and just kisses him. Tony is naturally confused but then he pieces it together.
“I missed you so much.”
They spend a lovely time catching up, remembering Watson, remembering the epic prank war, the chicken incident, all of it, and Steve is so thankful that their ‘civil war’ fight hasn’t happened and now that he’s here he’s going to make sure it never does.
He has to be careful and play everything right though. He can’t give away he knows more. So after he meets Sam and does his mission with Natasha he goes right to Tony, “I need your help” and because this is Tony, “Anything.”
Tony is there from the start helping Steve take down the portion of Shield that Hydra controls. When Steve comes to the part where he learns Howard and Maria (Tony’s very dear friends instead of parents) were killed he gets Tony on the phone right away to tell him himself. “I’m so sorry, Tony.”
Tony may already know because of Mycroft, but the fact that Steve tells him right after he learns himself means a lot. “Thank you for telling me.”
Bucky is captured and taken in and with Mycroft’s help he gets roomed somewhere underground and starts getting healed and his trigger words out. All the information originally dumped without a second thought by Steve and Natasha is filtered through this time around thanks to Jarvis in order to keep undercover Shield agents safe. The big plan is foiled and Steve knows for sure he did right trusting Tony because Bucky is already safe and sound.
When it comes time for Ultron Steve makes sure to keep Tony close to prevent it from being created. Ultron still happens though. Maybe Hank creates Ultron this time, who knows. There’s no arguing, there’s no “sometimes my team don’t tell me things,” none of it. When Wanda (and Pietro if he lives because things changed so much) tries to change her ways Mycroft intervenes in letting her join the Avengers without an evaluation. “This young lady shows a clear hatred for my brother. Letting her join without at least checking her mental state could cause incidents. I would hate for my brother to get hurt, Steven. You understand.”
Steve shivers the entire time and doesn’t argue to have a professional check the twins.
Mycroft starts letting himself get introduced to the Avengers here. Maybe Steve finally proposes. The get together bar-b-q where Coulson is brought in happens. Everyone is happy for the couple, everyone is happy in general. When Sam makes a comment about “Tony wouldn’t believe us” Steve quickly squashes it, telling him he knows his husband and he’s seen crazier things. He’s Sherlock Holmes for pete’s sake, Sam!
The accords are presented but instead of fighting this time Steve shows the barest hesitation, speaking his worries about “the avengers under someone’s thumb” to Tony. This time he knows Tony has the power to change the accords, and he trusts Tony to do just that with Mycroft’s help, but he can’t just jump in head first and agree. He has to show he doesn’t like it so they’ll actually do something. He hates acting ignorant but he knows it has to be done here. He won’t let ‘civil war’ happen again. He refuses.
Then finally Thanos.
