The final encounter of "Winterfell" is wordless, but packs one of the biggest emotional wallops of the whole episode, as Jaime Lannister finally locks eyes with Bran Stark, the boy he pushed out a window at the end of the pilot episode. Bran has never told anyone who was responsible for his "accident," but after Cersei hired Bronn to kill Jaime earlier in the episode, Jaime must know that if the Starks turn him away, he has nowhere else to go. He's played his last card by heading to Winterfell, and it's evident by his dismayed expression that he thinks it's a losing one.
What Jaime doesn't realise is that, with his vast knowledge of all human history, Bran is probably far more concerned with what Jaime's arrival means for the future than what he did in the past.
