Woo! It's been a while.
I believe that the protagonist in Glass of Water is Abigail. I think her struggles are the most central to the plot, and I think she is certainly the most likable character. I definitely think that Scribe wanted us to root for Abigail. Abigail is the one character who pursues a clear goal throughout the script and achieves this goal in the end of the play. Her goal, of course, is to be with Masham.
I will say, however, that I am not convinced that finding a protagonist or antagonist within this script is explicitly useful. During my analyses, I have not come across a point in which ranking characters in terms of importance or considering who has the most conflict in a script has served a purpose. I think that analyzing this play is possible without answering the question Dr. Fletcher has posed. I think discussing the group of characters who play within the main action as a whole is sufficient.
