Block B's P.O. sheds tears as his hyungs leave him to a lone attack by a giant flour bomb on 'The Great Escape'

On this week's 'The Great Escape' aired on August 19, the cast continued to puzzle out the mystery of the haunted house, trying to find key after key to escape each floor and level. When the cast discovered yet another ominously closed door in a storage room, the hyungs decided that it was a job for maknae P.O. alone.

P.O, being one of the biggest scaredycats of the cast, had a long battle with his inner self before he finally flung the door open. Nothing greeted him on the other side except a small closet space and a written talisman. However, seconds after the door opened, a huge flour bomb went off in P.O's face!

The poor idol was so shocked from the experience, he shed tears as he slowly walked out of the foggy room. Meanwhile on this episode, the cast members were able to take turns figuring out each mystery as they uncovered the hidden truth of a ghost family who haunted the mountain house.
