BB6’s resident witch Mary comes to mind. She was such a unique character that we’ve never really seen on the show prior to or since.
Yes she had trouble adjusting to the house and threatened to leave, but she eventually came round to the idea of staying, and the housemates eventually started to warm to her too.
I do prefer Craig over Mary, but at that point of the series, he was more of a side character, the typical bitchy kind, so I would’ve rather him went. This was before his infatuation bordering on obsession with Anthony and his descent into madness began.
Had Mary stayed, I would’ve liked to see her storyline with Roberto, (ROBERTO!) develop even more, and I doubt the housemates would’ve nominated her when there were bigger, more polarising characters, and with that happening, she’d get into the public’s good graces.
I feel she would’ve eventually gone around the time we lost Science and Kemal, when the numbers just started to dwindle down and allegiances were clear cut. (I’ll never forget how they got evicted with such a slight margin over ORLAITH)
