public Reply getReplyRef() {
        return entry.getReply();
    }
Returns the reply of the current child. It is VERY important that the reply returned by this function is not
reused anywhere. This is a reference to another node's reply, do NOT use it for anything but inspection. If you
want to retrieve and reuse it, call {@link #removeReply()} instead.

@return The reply.
