When Ahti ripped her skirt, it broke the tension the tugging had put on it, and Bast rolled when gravity pulled her downward. It was more graceful than simply flopping in the dust. Really, people didn't appreciate a good game these days. Ahti didn't have time for a little tug-of-war, but she had time to cause trouble? Her priorities were skewed.
Since the mortal woman had gone inside, and no one else was in sight at the moment, Bast reverted to a more human form. But she didn't get up. Waving the little bit of skirt in her hand like a trophy, because it was, she grinned up at the other goddess. It was a smug grin. In Bast's opinion, she'd totally won that round and thwarted whatever Ahti was up to.
Speaking of which...
“You weren't going to hurt her?” Bast snorted in disbelief. “You weren't going to help her either. You were going to drop a snake on her. Don't lie either, I saw you. You can't scare pregnant mortals like that. Well, I suppose you can, but you shouldn't. I didn't think even you would be so low as to hurt pregnant women.”
