Another perfect episode for me and to top it all from other episode. Irusu-sempai shows up again! to teach Chitanda how to
dominate 
good drawing skills Mayaka and good cooking skills for Chitanda. Oreki being Oreki -_- didn't even bother to go out of his little shelter. The ending points out that next episode its time for Oreki to walk out of his little room and start solving the mystery which surely makes Chitanda curious enough to bug him to move.
