Ms. Marphatia the new Maths and Science teacher of Sunaina's class after becoming the permanent teacher shows her reality. She treats the students even more strictly then Ms. Malpekar. She punishes them like primary class students like to keep finger on lips, to stand on bench and to hit on their hands through stick. Everyone again wants Ms. Malpekar to become their teacher instead of Ms. Marphatia. Sunaina watches in her dream that she is the participant of the show 'Hole In The Wall', where a spider shaped hole arrives pushing her in the pool. Next day, Ms. Marphatia teaches them about a rare breed of spider called 'Quashimoko' only found in Kongo, Africa, which can cause memory lose. Sunaina with Nina, Ritu, Sohail and Rohan makes a plan and spreads a rumour that Sohail's photographer uncle has brought the same spider to him. Then they all in front of Ms. Marphatia act as they have gotten memory lose including Principal Shastri who actually suffers from the same problem.
