I'm not saying what I'm thinking. Let me try this again. I'm going to kind of ramble below, because the language part of my brain is still sleepy from letting the programming part of my brain be dominant the last couple of hours. My apologies if his doesn't track well.
Diana and Artemis are from a society that does things differently than people do in Man's World. They're warriors born and raised. It's just as common for them to fight as a display of sisterly affection as it is for them to hug or sit down and have tea together, probably more common than that tea thing. However, what would happen if you were to grab someone off the street in the 1950's and ask, "Hey, you, what do you think of women who fight for fun and bonding?" I'm going to go out on a limb and say that they'd say it was abhorrent and unladylike. Almost sixty years later, such a question would get you, "Oh, I bet there Amazons, right."
This is how I look at Cass. Communication via combat isn't unhealthy for her, it's how she argues (in this scene with Bruce), how she plays (with Spoiler), but it's not the be-all of her character. She can communicate without fighting, as displayed by her various times with Oracle and Superboy. If this had been Stephanie or Barbara and Batman fighting over where her loyalties lay, they would have had a shouting match; with Cass, a sprawling fight that ends with an embrace is how she has a shouting match that ends with an apology.
Trying to use the way normal, vocal humans communicate and apply coping strategies against what Cass does is never going to fit, because in many ways she's as alien in how she thinks as Brainiac Five is.
That's why I like issue #50, because even though it defies some established continuity, it's one of the few issues where we not only see Cass communicating in her native form but also see someone listening and talking back. And I'm not saying Bruce is the best person to open up to about these things, but...I don't know of anyone besides Azrael or Shiva (No, no, no) who could have.
