Romance late?
Why is it only at the end of the film Prince Caspian and Susan show romance? That made no sense. Throughout the entire film, there were nothing going on between them. Then, all of a sudden, they share a measly little kiss.
shareNo, there were hints throughout it. When they first met, they both took notice of each other. They made flirtatious comments to each other throughout it too; Lucy even called Susan out on one:
Susan to Caspian when he tried to give her back the horn before she and Lucy rode off - "Keep it. You may need to call me again."
Lucy - "You may need to call me again?"
Susan - "Oh, shut up."
There was also the loving/longing look they exchanged after the war ended when they saw each other across the courtyard when Susan was walking with Aslan.
So, yeah, there were several implications.
