"Well, then, Arry, you shall not be late, shall you? If no one expects you and you've nowhere of importance to be, is that not so?" Not waiting for a response, Tyrion carefully scanned the surrounding countryside before deciding on a direction. He might not know where they were headed, but he did know that to stay still only invited trouble.
"Come, we'll go this way." He indicated the road with a nod and a wave of one short arm. "Good thing we have one another for company, isn't it? And even better that we are each armed." He'd noticed the sword, of course, and it remained to be seen if the lad were proficient in its use or not. But being no fool, Tyrion did not intend to discover that at his expense. Perhaps Arry would be of some use should they run into brigands along the way. Or Starks.
And that was the rub. For being of the North, the lad's allegiance surely ran toward them, did it not? He debated with himself whether to announce his identity, and decided to table that particular disclosure for now.
