Steph's watching Rachel, not the pebbles, and it takes her a second to catch up with the conversation.

"-- skip stones? Sure, I guess. It's pretty easy, once you figure out how to twist your wrist right." Instead of flicking the pebble that's in her hand, she tosses it to Rachel, picking up a new one for herself.

"I used to be better at it before. Now --" A shrug. "Re-learning. Like everything." Her right arm won't quite do it yet, and Steph doesn't want to force it, not when she's so close to healed.
