I gotta say, seeing Byakuya and Kenpachi just straight-up ignoring the biggest Espada to go at it themselves was actually pretty wild; I mean, who does that in the middle of a battle? But what really stuck with me was Unohana's conversation with Ichigo, because her saying he's the only one who hasn't seen Aizen's shikai suddenly makes him this huge wildcard, like he's the secret weapon they didn't even know they had.
