Sunbae making his way off Hally onto Vulgard seems plausible as either genuine or as a show, really.

but I think the way he came back to try and put hally back on the table before that is unlikely as w/w when you've got a strong team like that. It's possible he did it to get villa read and didn't expect the wagon to actually take off (so then shifted to vulgard) but idk, you can fit a narrative like that around almost anything if you want and that feels more like looking for a zebra than a horse, as benneh said earlier.
