Just a little FYI, while you've corrected the "Mysterious" and "Explosion" spellings in the white text box you've missed the "Explossion" in the black text box just above the white text box.

which includes a spellcheck plugin. While Notepad++ does not detect *.rpy as a "python" script file by default that's actually quite easy to fix:
1) Go to Settings -> Style Configurator, in the Language selection menu scroll down and select "Python", below it you will see a text box for "User ext.". Enter "rpy" (without quotation) into this box and Notepad++ will detect .rpy files as python scripts.
2) Go to Settings -> Preferences -> Language, on the far right are the Tab Settings, at the bottom is "Tab Size", make sure it is set to "4" then check the "Replace by space" Checkbox, and Notepad++ will use spaces instead of tab for indentation.
You can now open, edit and save *.rpy files directly within Notepad++ without any issues.
