chunk: Will meets back with Robin and a handful of his most trusted aides who survived the assault by the Celts. Instead of attacking Robin, Will informs him of the Sheriff's plans to marry Marian and execute Robin's men. Will continues to display anger against Robin, which motivates Robin to question why Will hates him so much. Will then reveals himself to be Robin's younger illegitimate half-brother; Will's mother was a peasant woman with whom Robin's father took comfort after Robin's mother had died. Robin's anger toward his father caused him to separate from her and leave Will fatherless. Despite his anger, Robin is overjoyed to learn that he has a brother, and reconciles with Will.
