The housemates speculated on what Mo was up to this afternoon after he went to the Diary Room and emerged an hour later.
While he was still talking to Big Brother, some of the group commented on how long he was taking.
"Holy moly!" said Darnell. "This has been the longest ever."
The group agreed and Sara suggested that he may be getting told off. "He does bite his microphone wire a lot," she offered.
However, Stu and Rex had less innocent explanations, with Stu saying: "It's a secret task."
Rex laughed and added: "Or maybe he's been evicted!"
"Well, it is a Wednesday, midweek eviction," Stu grinned.
Mo eventually emerged to demands from his housemates to reveal why he had taken so long. He joked that he had "fallen asleep" in the Diary Room and offered no other explanation.
