I can see Zoop's comment, but Zoop can't see mine. Because beehaw is defederated from lemmy.world but lemmy.world has not chosen to defederate from beehaw so it still gets the comments from beehaw users.
Actually because all these replies are to my lemmy.world account Zoop can't see this entire exchange, and I can't see it on my beehaw account either. I just had a brain fart.
