I guess I feel that he let his hormones rather than anything else dictate any strategy he had and once he was tied to April he seemed willing to let her and the rest of the alliance tell him what to do so he wouldn't mess up getting his nookie time.Unfortunately in the position he was in there wasn't much room to have a plan B if anything disrupted plan A.
Sure being the quiet one in the alliance got him further than the loud fighting ones, but if you align with obvious targets likely to get booted sooner rather than later about the best you can hope for is to the the last one of your group standing. Especially if you don't have any other options. I don't think he bothered to make much connection with other people in the house and hoped he could just sit pretty until the end being the least obnoxious one of the group he'd get the money if they didn't implode mid game which I thought seemed likely early in the game.
If he could have done something to hold them together and keep the volatility under control he might have been able to get that group to the end and win compared to the rest of them. Letting them go off and destroy themselves just so you won't be the target this week doesn't get you to the end. If you intend to get to the end with someone no one can vote for you have to still make friends with people other than the hated ones and make sure the hated one is protected enough to make it to the end game. Using them as a human shield and not doing much else just gets them booted too soon and you shortly after them.
I don't believe those are the people he would have gone with had he not been more interested in keeping up his sexual relationship with April than winning the money. Maybe she's his soul mate and what he will have won in the game is a life long marriage that will be worth more to him than any money. However, I doubt it.
I understand in those pressure situations you may develop feelings for someone. I think the wise course is to wait until the show is over to act on them. Just because something feels real in a very artificial situation you can't get out of doesn't mean that it is anything that will survive in the real world when you have real choices. Letting your sex drive determine who you chose to align with may not be the best way to pick people that will both stick with you and will help you get to the end.
