Seeing the smile was good enough for Helena for the moment. She could tell Claudia was still not back to herself, but the smile gave her hope that she was going to come around again. And at the very least, Claudia now had food for thought to kick around in her head when she wanted something to think about that was fun.
Helena herself had no specific ideas, though she knew what she should stay from so she wouldn't push Myka too far. After all, the point of pranks was to have fun, and she was fairly certain her and Claudia would be able to come up with something brilliant to unleash on Myka. The trick would be, of course, to pull it off without tipping Myka off about it.
Smiling herself, Helena settled in a bit more. "Just a penny for your thoughts there, darling."
