When reading the talk page of an item, there is no induction of what the item is about. The label and description should be displayed there, in the user's preferred language.
Example: I was recently referred to a discussion on https://www.wikidata.org/wiki/Talk:Q48685 - there is nothing there saying that the subject under discussion is "Judah - state established in the Southern Levant during the Iron Age". Without that context, the discussion cannot be understood.
