So you're going to pretend to be her brother's friend, Suede? lol. Aren't you maybe a little too old? In all the pictures I've seen of him he's a little kid. Brother's name is Alex i think but you probably know more than I do.
From the sound of things maybe you ought to bring some scuba gear =D. You can claim you were concerned that Cracky may have gotten stuck in the water. Suede to the rescue. =O
