At the beginning of avengers: Age of Ultron, Steve and Sam are talking about the house Steve says he cannot afford to have in Brooklyn. Sam replies "𝑾𝒆𝒍𝒍, 𝒉𝒐𝒎𝒆 𝒊𝒔 𝒉𝒐𝒎𝒆, 𝒚𝒐𝒖 𝒌𝒏𝒐𝒘" 'cause home isn't a place, but it's what makes you feel to be home {1/}

Later, when Steve is in front of Barton's treeshold, he hears Peggy's words from Wanda's vision again in his head, telling him "𝑾𝒆 𝒄𝒂𝒏 𝒈𝒐 𝒉𝒐𝒎𝒆", but he doesn't feel to be home, he feels so lost and lonely, so he doesn't enter it. {2/}

But at the end of the movie, when he talks with Tony about family and stuff, about the things he used to want when he was another person in another life, before he met the avengers and became part of them, Tony asks "𝒀𝒐𝒖 𝒂𝒍𝒓𝒊𝒈𝒉𝒕?" and he says yes, "𝑰'𝒎 𝒉𝒐𝒎𝒆" {3/}

He finally FEELS IT. And where the camera goes? To Natasha. Not Sam, his friend, nor the other new avengers. It goes to Nat. 'cause she is his home now. {4/}.

The deep layers this movie had, plenty.
