Yeah the whole Beth thing has me curious as well. At the end of the last episode when Daryl came out of the woods and was confronted by Michone, he then turned back to the tree line and said "It's ok, come out". That was leading me to believe that he had Beth and Carol with him. But then seeing the preview of Beth in the hospital, I'm a little conflicted in what's going on.
The group splitting up sucks though! Both Glen and Maggie are awesome. Glen is just an all around good guy to have around you and has the potential to be a great leader. Maggie (besides being hot!) is another strong person that anyone would be lucky to have.
