They are so bad together. There isn’t enough of a personality difference between them. I thought Emme Rylan’s more openly spoiled Abby worked much better with Devon (and they should have gone there with them with her in the role), maybe simply because ER played Abby with a stronger POV. He also worked really well with EH’s Chloe when she was a schemer. And of course his chemistry with Mishael as Hillary (but not with the more benign Amanda) is the stuff of legend.
Bryton is a great actor but he’s low-key in a way that doesn’t always work on soaps. And Y&R hasn’t written for him well (in the same way they often failed the gifted KSJ). He’s very natural and easy in his interactions but he isn’t a chemistry magnet in the way that MTS and BM are, and placing him with Ordway doesn’t give him opportunities to shine. But light a match under him (like his recent work with CK and TSJ), and he blows me away.
