In this episode big secrets are being revealed. Tilla traps Richie, Lili and Mira. Mira remembers back to the old times, when she was jealous at Tilla because Richie was dating her. We find out that Mira was the one who gave the poison to Parik so he could give to to Tilla... so Mira is the one who can be blamed for everyhing. We also find out that Dalma was the one who only knew about that but when she tried to stop Mira, she was pulled into a toilet and she wasnt able to do anything. In the end, Tilla and Dalma attack her.
(Plus: its weird that Dalma let Richie and Lili escape, isnt it?)
