Having watched the results show again after comments about Brendan being unprofessional and rude to Fiona, I think it anything she was extremely rude to him, it was obvious he was struggling to keep it together and she's busy grinning and wailing pathetically "do we have to" when they have to go for the last dance, and then to compound it she lets him walk on to that yawning dance floor alone while she goes off to kiss Craig Revel Horward.
If it was me I'd have wanted to thump her, he did very well to keep his cool, would loved to have seen his facial expression when she walked away from him like that, but sadly the camera hid it!!
I can quite see why his response might look un-professional but the truth is there never was much connection or chemistry between them so dont think it would be natural to them to hug at that point unlike Anton and Patsy or Zoe and Ian who are obviously very close and hug and kiss all the time. After all she didnt exactly comiserate with him, and even talking seemed hard for him when with Brucie and Tess.
So give the Boy a break he did his best with her, she would have driven the sanest, calmest person mad, and I for one look forward to him on ITT tonight.
Ps. Confession time, I seem to be smitten with Anton

how did that happen!! If only there was a man that was a combination of Brendan, Ian and Anton, now talk about hot!!!!!!!
