It's such a dramatic twist that Ichigo is the secret weapon because he never saw Aizen's shikai release, and I'm honestly a little unnerved by how intense Unohana was in the Garganta with him; I never realized she had that terrifying edge, especially when she pushed him to move faster. Now, I'm just absolutely hyped to see Ichigo at full power, knowing he's the only one who can really take on Aizen.
