I don’t think 318 is Gold centric, I think it’s Regina-centric or maybe even WW centric again (though that would be weird, having one in 316 and then 318). For one thing, I don’t think he’s going to be overly involved in that Cora/Leo story……. I see no reason for him to be and it doesn’t fit the timeline (and he didn’t know Cora before TMD).
We really need to see him in present – and with Belle in some regard even if they aren’t “together”. No Rumbelle at all except for maybe 315 (for an entire half) would be pretty horrible
