Brandon I think is getting a second chance (if this is true) because of Russell's attack on him during the reunion show. Jeff et al probably think he should get a second chance to prove Russell wrong. If that's the reason I'm against it though. He wasn't as bad as the other two Hantzes IMHO, but I can see why he's not liked.
(I doubt though he's hotheaded enough to get thrown out, and I doubt unless he physically accosted someone he wouldn't be ejected - especially when I saw Russell Swan and Ozzy DESTROY sets on the show, which in other shows such as "Big Brother" is an ejectable offense).
