I do find it odd though that Shen-shen said they were courting. Sunfolk traditions aside it seems fairly clear that Rayek is not courting her back.
She was actually just offended by Pike's truthfullness and was making up a reason. She didn't actually think they were courting. It was an excuse. You know, one of those things you say when you don't want to admit the truth. It was intentional. :D
