Watched BB13 in its entirety but can't for the life of me remember anything about Adam. Towards the end of the series, I got the distinct impression that Deanna considered she had it in the bag re winning. She struck me as becoming increasingly cocky. Unwise, I thought. When Luke A ultimately did win, I was not totally surprised. Always considered him the dark horse and was pleased for him.
Off-topic but without a doubt, the best bit that year was when Luke S made a fool of himself by falling for the fake PR / advertising agency offer of work after the series. Talk about vanity being one's undoing!
