Oh great, now there were two of them. Oh well, she'd warned them to be careful; they weren't really breaking any rules or endangering others, so she decided to let them be. Besides, there wasn't really anything she could do about it anyway, without resorting to force, and that certainly wasn't called for. Best just to let them have their fun and wait for Ronnie and/or Cath.
Emily didn't have to wait long; Ronnie arrived and got the rescue started. Responding to his question, she said, "Just a few minutes, I think. I wasn't the first to spot it; I think it was either that girl there" - she pointed to Abbie - "or Jean and Nikko. So Ronnie, how many people do you think we should send in the lifeboat? I'll volunteer to be one of them; I can keep in touch with the ship via the walkie-talkie."
