The ending of "The Handmaid's Tale"

Well. I think the ending was pretty weird. Confusing. The author did not really tell us if the Eyes were really going to save Offred or not (but I hope they did).  I also think it was weird that the old Ofglen hung herself.  At least Offred was safe though.  It was also kind of graphic when the guards were beat to death by the Handmaids, and how Ofglen kicked one in his head although apparently she was putting him out of sympathy.  It seems like Offred actually has a lot of power, being that Serena Joy found out about her and the Commander's trip to the club, but she still did not rat.  I kind of want to believe that Nick was an Eye and ratted on her for having sex with him after the time Serena Joy set it up.  This book was confusing towards the end, but I still like it.
