What’s the lie your character says most often?
Urudu technically doesn't lie because of some faerie bullshit but it is intentionally delulu. It puts aside its own desires and pretends not to have them, while still being entirely cognizant of its self-repression. In a way it lies to itself, for a long time.
2. How loosely or strictly do they use the word ‘friend’?
Very strictly. It has high standards! I mean, if you're not willing to die for its friendship, what sort of friend are you really? Note that this is only after it manages to make one (1) friend, where it previously considered any form of companionship too costly a prospect to consider. There is progress...however slight.
3. What subject / topic do they know a lot about that’s completely useless to the direct plot?
All the ways to take the Lord's name in vain 🙏.
