On a reply post, it is common practice (possibly established by Twitter on tweet permalinks) to display the context of what the post is in reply to, including linking to that original post with rel-in-reply-to.
Why show reply contexts?
How should reply contexts be marked up?
<div class="h-entry"> <div class="p-in-reply-to h-cite"> <p class="p-author h-card">Emily Smith</p> <p class="p-content">Blah blah blah blah</p> <a class="u-url" href="permalink"><time class="dt-published">YYYY-MM-DD</time></a> <p>Accessed on: <time class="dt-accessed">YYYY-MM-DD</time></p> </div> <p class="p-author h-card">James Bloggs</p> <p class="e-content">Ha ha ha too right emily</p> </div>
Why use h-cite instead of h-entry for reply contexts?
Why not use h-entry in addition?

In order of deployment:
Though one advantage of storing and showing a reply-context is freezing the original context of what you're replying to, it may make sense to accept some updates.
