And at the end of the book, Radha asks if Amber and Hex are married when he has seen them flirting with one another (page 312). In Fault Line, Hex writes something to Amber on his Palmtop, near death, but he deletes it before Amber can see. In Untouchable, when Hex is trying to find music on his palmtop to calm Alex down, we see that one of the albums there is named Amber, which seems to be another small indication he is interested in Amber. In Hostage, Amber kisses Hex on the cheek just before she gets taken hostage in the underwater mines. And in Desert Pursuit, Khalid can see straight through Amber, forcing her into admitting that she likes Hex. She can't let anybody know that she is affectionate towards 'Code-boy', so quickly refutes Khalid's statements, however both Khalid and Amber know that she does have a soft spot for Hex. Li and Paulo In Survival, both Li and Paulo take an interest in each other, flirting on occasion. Li is very desperate to find Paulo in Rat-Catcher and Paulo gets very angry and starts to beat Alex up when Li disguises herself as a boy to follow the notorious slaver known as the Scorpion in Desert Pursuit. More evidence of their relationship appears in Blood Money when Li tried to get Hex to admit his fancy towards Amber, by saying "you probably wish Amber was here instead of me," but Hex retorted with "you probably wish Paulo was here instead of me." Also, when they volunteer to build a school for an Indian village during Blood Money, they flirt with one another, flicking mortar playfully at each other, Radha comes up to them and asks if they are married. They were both very surprised at the question and they quickly denied it. In Desert Pursuit, Chris Ryan tells us that Paulo was more fond of Li than he cared to admit and he has been known to give her a fond smile Alex Alex doesn't seem to have any girlfriend in any of the books, considering there are only two girls in the entire group, both of which are more interested in the other two boys. In Survival, he kisses Amber after she gets medicine to save Hex, but this is the only indication that he has any feelings for anyone in the group. Books Survival (2002)
