I found Luke to be a fun and memorable character right off the bat with his hyper-sexuality and Texas/American patriotism. It was interesting to watch how he pushed the boundaries of Asterion's ideal hotel decorum, and how these ideas made all the guests around him uncomfortable. Luke is just so forward, so easy to read, such a fun stereotype, and I think this is a good thing especially if you are planning to introduce more characters and more cultures in the future.
