"Ah!" Agent 3 looks up to see that Usagi has disappeared. If she was back home, she might have thought that she Super Jumped away. 3 continues walking and looking around.

Eventually, she does arrive at Thistle Do Nicely and peers into the window, hands on the glass and face almost pressed against the pane. 3's more impressed with the variety of colors in the shop over realizing that Usagi is there now.

... Hopefully she doesn't leave any hand prints all over the glass.
