Ace continued to watch the man walk while listening to Senna. "Actually, I'm quite positive Lacy can take care of herself on a typical day. But, seeing as she's been 'emotional' lately..." He murmured, shrugging to end his sentence. When she mentioned 'taking out the trash' because he was involved, the ginger gave a lopsided grin. "It almost sounds like you care about me," he joked. He placed his hand over his heart for dramatic effect. "Quite flattering actually." 
Ace crossed his arms, tapping his fingers against his skin. His hazel eyes shifted back to the man in the black suit. "I kind of want to interrogate him," he stated under his breath. "Curious as to who sent him." He was just thinking aloud at this point.

Lacy surfaced as well, smoothing back the strands of dark hair away from her face. "It is very nice," she agreed, grinning back at him. She let out a small laugh before submerging herself again. This time, she swam underneath Dick's feet to tug on his foot before swimming as close to the bottom of the seafloor as possible.
