Stephanie's monologue about him saying he has too many enemies who would love to get you to get to him:

You say your life is dangerous and you don't want to leave behind a widow? Congratulations! You've won a live human with its light sniffed out

Your life does not lend itself to a relationship? Lest the enemies come after them?

News flash!

I'm already associated with every SINGLE one of the Merry Men, most of whom I assume has done some type of contract/ in the wind deal with Uncle Sam.

Any enemies of yours worth their salt would case your day to day habits for at least a few months

I'd doubt they'd miss that you are at every single ONE of my accidents. Gee, they must be dumb to not catch that I'm important to you regardless of whether we are in a relationship

Having the streets and underworld know myself as "Manoso's woman" doesn't help your case anyway since I assume they would interact with the underworld to gather info, maybe disguise as a concerned citizen and ask the cops who I am and why are there so many men in black every time this happens and deduct reasoning from there

So I ask you again, are you really going to stick with that argument? Because either way, I'm involved in your life...

That should give Ranger something to think about.
