So, I initially found US Agent/Walker’s blank expression after Val’s announcement to be incredibly funny. It was like he just wasn’t totally all there in that moment, or was completely spaced out & confused.

After some rewatches and a few shower thoughts, I realized that I felt that the ending of “Thunderbolts*” shared some parallels with when Walker was first announced as the new Captain America in “FATWS.” A very similar moment of a newly government-funded hero(es) being introduced to the world with a familiar & prestigious title, yet his attitude contrasting greatly between projects—from a prideful demeanour and cocky wink, to him seeming more distant jaded.

And the negative outcry and signs of rejection after they become the New Avengers feels like familiar territory to when he struggled with the pressures of adopting such a renounced title and heroic role and living up to the name (even to the point where his need to appease to everyone’s expectations felt like an unhealthy obsession). So I wouldn’t be surprised if this moment brought back a bit of his past trauma.. Almost like a “not again” type of reaction. Though I also infer that because of this experience, the novelty of being an “Avenger” wouldn’t really mean much to him anymore as much as just being recognized as true hero does, and so he doesn’t show as much excitement as Alexei & Yelena did.
I feel like Walker’s reaction to the “New Avengers” moment mirrors his Captain America announcement.. now he’s a bit guarded/unfazed due to his past struggles with imposter syndrome and the trauma that followed—a moment of déjà vu
