I would guess it should be the same as the sirens - if you're talking about the S4 finale and specifically want to mention the guard introducing the Maretonian fags at the start, that sounds like it would probably be allowed. But in FiM he's literally just a completely random background guard that's arguably far less important even than whatever unnamed guard announces the Crystal Empire's return in S3. Anything beyond that is about the EqG counterpart, and would therefore be banned. Might be worth clarifying with the staff, but to me this logically seems exactly like the sirens.

The point is that FiM introduces some plot-relevant characters of a new species. EqG happens to feature characters which are canonically the same ones within EqG lore, but basically have nothing to do with the FiM appearance - different species, different characterisation entirely, there's pretty much nothing in common. I haven't watched any EqG but if you're saying they never even physically transformed into fish forms during EqG that just strengthens my argument. Ultimately, it's possible to discuss the S7 finale plot device without any reference to EqG. If EqG didn't exist, the S7 finale could still work completely unchanged.
In contrast it's not possible to discuss Sunset without any reference to EqG, because within FiM she only exists as literally just a reference to EqG, a cameo. If EqG didn't exist, her cameo in FiM couldn't exist either. Besides, she canonically appears in pony form within EqG, so there's no separation by character or species or anything else. There's no "FiM Sunset" as opposed to "EqG Sunset" which could be discussed separately; she ONLY exists within the context of EqG.
