According to a leaked report, Meemaw will meet Amy but they don't hit it off, as Sheldon's grandmother seems to have an axe to grind with her over their break up in season 8 finale. The episode will also find Sheldon speaking in Amy's defence but Meemaw lets a little secret of his slip — that he has a ring for Amy.

So, Amy will finally learn that Sheldon was actually planning to propose and that he has a ring for her. Previously, executive producer Chuck Lorre and Steve Moralo hinted that the ring will come into play in the future episodes.
