question: Who faces Sir Thomas Colville in a joust?
context: At a jousting tournament in 14th-century Europe, young squires William Thatcher, Roland, and Wat discover that their master, Sir Ector, has died. If he had completed one final pass he would have won the tournament. Destitute, William wears Ector's armour to impersonate him, winning the tournament and taking the prize.
  Although only nobles are allowed in tournaments, William is now inspired to compete and win more prizes. Roland and Wat would rather take their winnings and leave, but William convinces them to stay and train him to joust. Along the way to his first tournament in Rouen, the trio encounters a young Geoffrey Chaucer, who is also destitute and agrees to forge the patent of nobility that will allow William to enter under the assumed name of "Sir Ulrich von Liechtenstein" from Gelderland. At the tournament, William is brought before Simon the Summoner and Peter the Pardoner: Chaucer has a gambling problem and is in their debt. William demands Chaucer be released and promises payment.
  In the course of competition, William's armor is damaged very badly. He goads Kate, a blacksmith, to repair it without payment and goes on to win the tournament's sword event. In the joust, he faces Sir Thomas Colville, who withdraws from the tournament after being injured by William, though they exchange a ceremonial pass so that Colville can retain the honor of never having failed to complete a match. The proceedings are observed by Jocelyn, a noblewoman with whom William has become infatuated, and Count Adhemar, a rival both in the joust and for Jocelyn's heart. In the final joust, Adhemar defeats William. At the prize ceremony, William vows revenge on Adhemar who then taunts William by telling him that he has been weighed, measured and found wanting. William then uses some of his winnings from the sword event to pay off Chaucer's debt.
