Bran hangs out with Meera and Jojen who are his new best friends now that everyone else has gone home after the big party. Apparently Jojen has "greensight" which is some sort of ESP power, and they think Bran has the same power on account of his dreams and wolf mind-melding.
Bran is so freaked out by this he mind-melds with Summer and she attacks Meera and Jojen, but they seem pretty cool about it, because Jojen knows this is not the day he dies.
Maester Luwin is highly skeptical, being a man of science, but there comes a point when there is so much evidence you ought to start believing in magic. One of these days Bran will make a solid prediction about something he could not otherwise have known and then everyone, including Bran, will believe in his magic powers.
