I'd just get on with the routine of the house, gathering up the views and suspicions I was hearing.

If you try too hard to hide something like that, you actually can expose yourself more,the only thing that is certain in the BB house are the tasks, the routine set by BB and the surprises they spring.
Concentrating only on those could even until the time comes to decide something,leave you almost not thinking you actually were the one with the power.
