Blake walks into his dressing room and reads a note.
Here's what is says:
Dear Blake (and Ness),
Please leave the competition or danger will come upon you
Blake quickly runs and informs me and Ksxx as we are talking to pairs competition's nurse. We all read the note, but it is typed and there are no fingerprints besides Blake's. The nurse tells us that some combatants have hypertension, and that one bottle of her prazosin did go missing just before last round. She also says only the 4 pairs left on the suspect list were in the day before last round.
