If Bruce looks attentively enough he might notice the flicker of amusement that passes through Bucky's eyes as he watches the other mans adventurous tribble try to climb Mount Banner. Then he's nodding in agreement and gently slipping his own pet back into his pocket where it can do no harm so he can pick up his knife and fork to finish his current plateful of breakfast. "Okay."
