Dorathy has named Neo and Kiddwaya as the two male housemates she would never trust in the house.
Her reason for not trusting them is that she finds them mischievous and probably sneaky, mentioning Kiddwaya as an expert in that area.
Last night, while conversing with Ozo she recalled an event where Kiddwaya embarrassed his own friend and greatest ally, Nengi, when she followed Ozo into the diary room when big brother called him.
Apparently, Nengi did not follow him into the diary room, she was on her way to the bathroom instead.
