Because she has two Steves working for her (Rogers and McGarrett) Natasha has taken to calling them Thing 1 (Rogers) and Thing 2 (McGarrett) when addressing them in the same room and such.
Natasha found Clint literally in a dumpster and took him in and gave him a job when she found out he had particular skills to help him get on his feet again.
She has a habit of taking in quote strays and helping them out. She knows what it’s like not to have anyone. She’ll make them earn their keep though.
Because of past experiences Nat doesn’t allow herself to get too attached to any one person. She has feelings for all her lovers or benefit buddies as she likes to call them to some degree, but she won’t commit to anyone. It’s easier that way and she doesn’t want to ruin the allure of their performances either and even the regular male staff have an allure to them.
James “Bucky” Barnes, after leaving the stage became Nat’s shadow (along with head of security) so she could feel a bit more secure as she still isn’t fully over the events that occurred in Russia even if she won’t admit it.
She has a little bit of a drinking problem, but luckily a high tolerance. Essentially drinks and sex are her coping mechanisms for dealing with her problems.
While she’s nice and gives “favors”, she doesn’t play favorites parse. And if you fuck up, she won’t go easy on you just because you might be in her bed once in a while.
