Hilda's mouth opens and closes in an attempt to formulate a response to the very valid question. Fine, he's got her there. There hadn't really been any particular rhyme or reason why she had decided to pursue him to the top of the diving cliff apart from being completely shocked that it was him in the first place. Now that said shock has worn off, she's left with little steam left.

Had she not been already bickering with someone else, she might have had more nonsensical reasons, but as it stands she doesn't. Maybe Altaïr had the right idea to dive off the cliff. "Of course I didn't come up here to interrogate people," she finally manages hotly choosing (for once) to back down. "I'm just surprised that's all."

With her arms crossed she looks like the spitting image of a younger her when she didn't get her way. Instead she chooses to change the subject - they're here now, aren't they? "Where did you learn how to dive off a cliff?" Because that's what she assumed he was coming up here to do in the first place before she had so rudely interrupted him.
