Harley is former military himself so he can totally get on board with one of the wives actually not needing any training from him. It's okay Cee, Harley won't make any age-jokes (she's actually older than him, whaaaa) .... well he won't do a hella ton of them at least. Just spread them out. I can see him taking a quick liking to her too, Badass Texas girl? Hell yeah!
