Plans are things Steve's good at, in general. He doesn't always stick to them but he's gotten a hell of a lot of experience over the years in drawing up battle tactics. Making a working plan and leading people to see it through. Improvising when things can and do fall through. But Steve's never been the Brains of the Avengers. When it comes to theoretical out there sciences he has to take a step back and let Bruce, Tony, or anyone else with a niche expertise step up to figure things out when things get above a certain level. When Scott was talking about it Steve almost thought he could keep up but the second actual numbers started getting thrown around he's been overwhelmed with things he didn't even know he should have been asking all being discussed while he stood back.

Not that he's had the easiest times of staying here in the present since Tony came back. Since Tony brought him The Shield.

Something he hasn't touched in years now. How can anyone expect him to use it? It's always felt like it was made for his hand to wield it but somehow Steve just doesn't feel like he can. There's too many memories tied to it. Too many regrets. The complex is more full than it's been since The Snap, with more Avengers in it since damn near before The Accords even if the rest of the staff is gone.

Steve can't simply walk off and zone out to his own Better Days when he feels like it's all closing in on him. He does spy Thor wandering off though. If anyone knows a quiet place to sit and ruminate it's going to be him. No one notices when Steve excuses himself from the briefing room turned planning area to head outside and catch some fresh air. He wasn't adding anything to the discussion anyway. No one will miss him for a little while. It takes him a bit to figure out where Thor's gone but climbing up after him is at least as easy as it ever was.

"Budge over, will you? I need to get away from the racket for a few minutes."
