I had a similar need – to show the user’s bio on their replies – so sharing my solution here, a simple function created after having a look at this nifty little plugin by Robin W.

function show_bio_bbp_replies () {
$user_id = bbp_get_reply_author_id( $reply_id );
$usermeta = get_userdata( $user_id, 'description' );
echo '<p class="bbp-reply-user-bio">'.$usermeta->description.'</p>';
}
add_action ('bbp_theme_after_reply_author_details', 'show_bio_bbp_replies');

Thanks Robin, sounds like my issue to fix.
