I do not actually ship Ichigo and Ishida (does anyone?), but I have to note for the record that in the post-Menos Grande episode, the two of them have a classically awkward day-after scene.

In a similar vein:

Renji: "My God, you have the biggest zanpaku-to I've ever seen!"

Ichigo: "Oh, really, so it's unusually big, then? I just thought mine was bigger than Rukia's."
