Susan has just melted down another group of stone soldiers when her brother falls from the sky- “Miraz has Caspian locked up in the tower” Peter tells her as he reaches out to her “Edmund and Lucy are meeting us there”.
Susan sighs as she holds onto her brother, this has never been her favorite mode of travel, and the winds come to gather them up just before the next squadron of stone soldiers would have crushed them.
When they arrive their siblings are already there, stone soldiers pierced by twisted roots or wet and smashed to bits lying in a circle around them, and together the four of them storm the tower and rescue the prince.
