Arthur reads a lot about magical curses and thinks it's funny to pretend something happened to him. A part of him is curious to see what Merlin will do, if Arthur acts strangely.
Several, very unexpected things happen a lot quicker than Arthur would have guessed.
1. Merlin seems to notice that Arthur's acting strange immediately. What Arthur thought would take at least a week, took Merlin less than a day.
2. Merlin doesn't seem to have a problem with illegal research
3. Merlin covers for Arthur and does not inform the King
4. Merlin is willing to ask druids or magicians for help
5. Merlin is actually strong enough to manhandle Arthur to keep him from running off
6. Merlin seems ready for murder in order to protect Arthur
7. Merlin seems used to it all
8. When Merlin finally uses magic, Arthur isn't even surprised anymore.
9. It's actually kind hot
