"Can you sing another one?" J.J. asked Dave as she watched the profiler carefully in case she was going to far. She wanted him to open up about whatever had been bothering him lately but to do that she had to put the perfect amount of pressure without scaring him off. Luke was there as he back up and she figured the fact that he was also former military might help just a little bit.

"Yea Rossi, I only know the Army ones or at least versions," Luke added in trying to encourage Dave who looked at them both with suspicion before nodding slightly.

"Alright I'll do one more but that's it," he told them as he leaned back in his chair.

Mama, mama can't you see?

What this Corps has done for me?

Put me in a barber's chair,
Snip, snap and I had no hair,
And if I die in a combat zone,
Box me up and ship me home!
Put me in a set of Dress Blues,
Comb my hair and shine my shoes,
Pin my medals upon my chest,
Tell my Mama I did my best,
Mama, Mama don't you cry,
Marine Corps motto is "Do or Die!"
Say, left, right, left,
Left, right, left,
Low, right, left,
Lefty, right, low.

Dave finished the cadence proudly, a slight smirk of satisfaction at the fact that he'd remembered most of it. Of course there were many other verses to this one but he felt he'd done well remembering the first one and if Luke and J.J. were anything to go by he had indeed impressed them. That being said his happiness once more dissipated after a few seconds and he thought about Vietnam once more and Desert Storm as well.

J.J. took a slight breath and decided to go with an under the radar question first so as not to spook him. Something was bothering Rossi and she was going to have to play the long game to find out what it was.

"How long were you in the Marines for?" she asked him with that I'm not going anywhere with this look.

"22 years," Dave answered after a moment's hesitation. He wasn't sure where this was going but he didn't like it.

"Wow, you must have ranked up really well," Luke cut in to take the tension off of J.J. Somehow it worked and Rossi relaxed a little at Luke talking almost business about it.

"Sergeant Major, E-9," Dave confirmed a little more relaxed that this wasn't going to go super personal.

"That couldn't have been easy to get to," Luke prodded and immediately regretted doing so because Dave shut down faster than an engine out of oil.

He didn't know how to respond to that other than with a "yea, it was."

J.J. watched as he stared at his desk and wondered if she could get him to sing another cadence. They seemed to relax him a bit, plus his voice was kind of soothing.

"Can you sing another one?" J.J. asked him quietly.

"Why?"

"I don't know, it's just nice to listen to you sing something other than jazz," she said honestly.

"I think I can pull out another one," Dave told her as he relaxed once more.
