You are asking for "silliness" not really Humor. There's lots of humor in the game. There's less of the silly natured things like Sir Lora etc. (Although get yourself speak with animals, and have a chat with the squirrels, they are a hoot)
Well yeah it's silly but the lines were pretty funny. Silly and funny can work together. There was also a purpose to that pair as they would give you goodies throughout the story. They were more of a companion in that way than an actual PC.
Yeah I'll have to make sure to try out speak with animals after the next big content patch - definitely.
