Kelsey does not deserve to win
Tim deserves to win out of the 3 left, but if it is Brothers and Kelsey then Brothers 100% deserve the win. They entered the game as a duo, and still made it to week 6/7 before being nominated. Watch the first few weeks, they had a great social game. Yes maybe them being voted with Nikki as top 2 in the HOH went to their head, but they still did well before then, and after they won competitions, I mean they have 4 POV's and 3 HOH's and are now hold the Canadian record for most competition wins; very could well win another HOH as well. Strategically, sure they have not been the best, but Kelsey has been the same as well.
If they are the final 2, the jury would have to be extremely bitter not to see the brothers deserve it over someone who was all ready evicted in week 3. Like the above poster said, she probably has Raul and Jareds.
The other votes could go either way, but I could see some voting Brothers to win.
