Bruce: I want what you want, but we need the nobles.
Wallace: We need them?
Wallace: Nobles. Tell me, what does that mean to be noble? Your title gives you claim to the throne of our country, but men don't follow titles, they follow courage. Now, our people know you. Noble and common they respect you, and if you would just lead them to freedom... They'd follow you. And so would I.
Wallace is trying to convince Bruce to unite the clans and join him in his fight against the English.
