When it comes to making a relationship work, I think the most important factor is timing. If timing isn't on your side, then most likely the relationship is dead on arrival. Throughout this episode, timing is a reoccurring theme, and you see several of our relationships either fail, blossom, or get put on hold.
Despite my strong opinions about flirting with ex territory, once I saw the love that Glenn and Rebecca share, it was hard not to root for them. They have something really genuine and special that many people search for their entire lives. But it makes me sad to see that their stars haven't completely aligned yet. Whether it be geography or careers, something is keeping them from pulling the trigger and going for it again. I know Glenn has said that she means more to him than any other woman he has ever met, but sometimes men aren't smart enough to realize that they could lose the love of their life while they kill time and make their minds up. But in the meantime, he has plenty of girls in bikinis and high heels to keep him company! (Don't even get me started on that pool party again!)
