As I mentioned in crackchat - it mostly just becomes an epic sword fight between Gamora and Obi-Wan Kenobi while the others watch.

Dick: "shouldn't... we help?"
Fives: "Nah kid, trust me you don't want to get in the middle there."
Simba: "Do we have to fight each other?"
Dinah: "Tell you what, we'll let those two fight it out and then we can gang up on the winner when he or she is tired."
