From 11:00PM PDT on Friday, July 1 until 5:00AM PDT on Saturday, July 2, the Shmoop engineering elves will be making tweaks and improvements to the site. That means Shmoop will be unavailable for use during that time. Thanks for your patience!
Ophelia is a super minor character here. She is the daughter of Polonius, and Hamlet may or may not be in love with her. Claudius uses her as a tool (like Ros and Guil) to try to figure out what is wrong with Hamlet.
