Barda did not consider the fight with Cassandra to be 'awesome.' Then again, she lacked the teenage understanding of the word and the overall concept. Speaking of concepts? She had very little concept of exactly how fragile humans could be. Scott had taken her away from the SWORD agents before she had been able to do more than a little danger do her basis for comparison was not on par with reality. She recognized the familial bonds if not a familial appearance between the two as she stood behind Scott's chair, not quite comfortable (or knowledgeable) enough to sit in a civilized fashion for coffee.
So she stood behind his chair with her arms crossed and didn't really have to work to look formidable, even if she weren't trying to intimidate Bruce. The coffee alone was awkward enough for her as it was. She watched. Barda was doing a lot of watching and she didn't like the uncertainty that came with being in Earth. Her mission wasn't supposed to go like this. It was suppose to be easy. A splash of violence, some bloodshed maybe, and then Scott Free hauled back to Darkseid. She had expected some difficulty in finding him - but not in letting him talk her into drinking something that could be poisoned in some earthling's home.
Though it tasted good, at least. If Scott were trying to distract her, it was working. Barda wasn't sure what to make of the coffee. The taste was entirely foreign - and surprisingly good. Coupled with the unspoken dialogue happening between father and daughter, Barda was momentarily distracted from the task at hand - until they started talking again.
"You are stalling, Scott Free," she grumbled in returned. Barda was not familiar enough with Earth expressions to get the pun in his name. "We are not staying."
That was turned to Bruce, as the coffee was forgotten.
