Frodo Gets Drunk and Screws with His Neighbors
Caspian has a royal blast meeting all the talking animals. He's right kingly and socially very nice to the magical talking animals who have no problem with making him their king almost at once. Needless to say there is no argument over whether Caspian should be king or not. Everyone pretty much accepts the "son of Adam should be king=Caspian" bit. The book explains that Narnian rodents are bigger, something the movie failed to do, leaving everyone thinking that Reepicheep might possibly be a sewer rat.
During the war meeting, Caspian pretty much calls all the shots. This was the biggest problem I had with the movie. No where in the book is Caspian ever waffling. He's royal, he knows it and he acts like it. He's like a younger Peter. He's the one ordering the Narnians on battle plans. He bows to superior wisdom, but he never backs down. Anyway, the Narnians decide it's time to have a jam session with Queen Susan's horn and Trumpkin goes off where they think the old kings and queens might show up.
Trumpkin finishes his flashback and is thoroughly disappointed that the kings and queens show up at the Tiger Beat crowd age. Edmund challenges him to a fight. Trumpkin is actually the one who comes up with the DLF line and only after Edmund defeats him does the DLF nickname become Trumpkin's. Susan hates all the fighting, which is amusing considering she had the highest body count in the movie. She also out shoots Trumpkin in an archery match and Lucy heals him with her miracle juice. Trumpkin is thoroughly convinced and they all row off to meet Caspian.
