Some days Blues wonders what the hell is wrong with Hinoto-Ri and why he even bothers leaving his apartment on those days, and today? Is looking like one of those days.

Since he had come to the park to just relax outside, by himself, that isn't going to happen when he hears the yelling robot before seeing him. Then when Cutman ran past? That's when Blues actually paid attention.

And promptly wondered, once more, what the hell is wrong with Hinoto-Ri before he'll make a simple attempt to help the other robot.

By shooting at the flying scissors.
