Kimmo (pictured above in the Diary Room) — who was appointed as the "coach" of the rest of the HMs who navigate the obstacle track round and round — got a letter from Big Brother.
BB has a secret task for Kimmo: if he manages to encourage all other HMs to break their personal "number of laps per day" record tomorrow, everyone — including Kimmo himself — gets to read a letter from home.
If only
some of the HMs manage to break their personal record, only those persons will receive their letter, and Kimmo won’t get his.
Kimmo is not allowed to disclose this information to his housemates.
