Ron watched Hermione look from Leila to Sirius and back again, then grinned. "She's fine, Mummy. I don't think she's going to be singing the lyrics when she's at the Burrow and shocking Mum into a heart seizure," Ron paused at that. "Come to think of it, I'm sure the Twins did that at least once, so we're safe there too."
Ushering her to a booth with a hand to the small of her back, Ron watched Leila clap when she recognised Sirius on the stage. And then, once she'd made her presence known, proceeded to dance for them right in front of their booth.
"Such a shy, cautious child, our girl," Ron winked at Hermione.
