It's Crush/Djinn/Damian. It's pretty obvious that Crush is crushing on Djinn, and 24 indicates that the attraction is mutual. Crush got all pretty and starry eyed when Djinn caught her. Crush is the one constantly making disparaging remarks about Djinn and Damian interacting in the confused prepubescents displaying interest way and calling attention to it. She got hostile, upset, and hurt by the implication that she actively endangered Djinn and would be kicked off the team in 23. Her reaction to Damian's lecture was very similar to Djinn's reaction to Emiko's lecture. Except she's not a terrifying eldritch abomination, and therefore took it to heart instead of getting pissed and warning Emiko to back off the cockblocking or else.
Although I wouldn't rule out Kid Flash and Roundhouse crushing on Crush. I would never rule out KF. Despite being a whiner that boy has game. Raven, Tanya, who's next in the list of tragically unavailable girls he'll be attracted to? Emiko obviously, and Crush who are both not available for heterosexual romances.
However Crush/Djinn is all over the place. It's as obvious and heavy handed as Damian/Djinn.
