Personally, I don't think there's any cannon relationships there, it was an alliance commonly formed by the district 1 and 2 careers, and they always band together, help each other out until they are the last ones remaining, then fight to the death.

In the book it clearly said that when the tracket jackers fell, everyone booked and didn't give Glimmer a second glance as she died, including Cato.

Since Cato and Clove are from the same district, I don't deny the possibilty that they have some kind of bond but it might not be romantic. He was said to be in pain when he saw her on the ground dying, but it could be that he didn't want to lose a friend and treasured ally, since the Gamemakers had just announced that two from the same district could win. One way or another, he did seem to care for Clove, and risked being attacked by Thresh to try and save her, unlike his complete abandonment of Glimmer (in the book, yes, in the film they did appear to be flirty and had chemistry, but the movie also strayed terribly far from the book in almost every other aspect).

So as a completely fan/uncannon ship, I would say Cato and Clove, even though they ignored that in the movie and went straight for Glimmer and Clove, but movies are notorious for doing that, shipping whatever looks better than what's actually written.
