Of course Duo would be a natural at improvising tactical gear from cheap household materials. Heero isn't surprised in the least that he caught onto his intent so quickly. Were he better at delegation, he might even send Duo to do the job himself.

"Mn. You go ahead and choose the apartment."

Not only does Heero trust Duo with that task, well... of the two of them, he suspects Duo has the strongest opinions about the type of place he'd like to live. He seems to appreciate comfortable living in a way that Heero doesn't quite grasp.
