For there to be a love triangle Diana has to want to be with Orion or have feelings for him. I frankly don't see it at all.I do see guy who is written with the depth of Guy Gardener and not very good characterization of the Dog of War. Disappointing actually.
He inappropriately touched the character gets her dna.(rolls eyes) Newsarama's interview with Azzarello, he admits did not let Diana slap Orion right away for it because he just wanted people talking. So the whole scene was weak anyway. Of course, Diana would/should have put him in his place. Orion could have gotten it from her back or shoulder but hey that's not sexist enough is it and what a great way to force tension...dickish behavior. But then I would have thought any woman would react like Diana so not sure what is so special or entertaining there. Being called Legs, smirked at, spoken down to, ass grabbing...Wonder Woman wants that? Secretly sort of digs that? I doubt it. Not the WW I have been reading or the empowered strong woman I am a fan of. But then I don't know what Azz is thinking. Maybe he thinks otherwise.
Orion and Wonder Woman are the least likely to work because end of the day Diana is a character whose mythology is not solely about Gods, god chasing or godly politics...but a young woman finding her place in our world and learning to live and adapt to it and be one of us even while protecting us. Azz's WW works as a single story after the dust settles here the character needs and will to get back to her super heroics. Orion is out. He's just here for high jinks. Clark and Steve are the only serious and worthy contenders for her affections.
