We now show if a queued or flagged post is a reply to another when in the review queue. It's especially helpful for queued posts where normally they are linked to the topic where they are created, and you have no context about the reply. Note that this will only apply to new queued posts going forward. Previously queued posts will not show the "in reply to"
